For the upcoming Israeli election, divisions on the left are not the problem

Israel’s general election has been set for 9 April. This election is both “late” and “early”. The term is four years, and this election will be more than four years after the last election (which was in March, 2015). Yet under Israel’s Basic Law provision on election dates, the date for 2019 could have been as late as November. Nonetheless, the Knesset passed a bill in late December setting the election date.

All indications, at least for now, are that the Likud and its leader, Benjamin Netanyahu, will remain at the head of the government following the election. Polls put Likud far ahead of the second party, which in many polls is a new entrant, Israel’s Resilience, founded by former IDF chief of staff, Benny Gantz. The real question is who will be the coalition partners. Both the governing “nationalist camp” and the opposition feature numerous parties, as usual, but also splits, including several new entrants since the election was announced.

There is often poor understanding of how Israeli politics works. To a degree, that’s understandable, as it is a complex political scene (and society). However, there is really no excuse for a major publication like The Economist getting it as wrong as it did in its 3 January edition.

The author of the piece shows a poor understanding of the dynamics of proportional representation and parliamentary government, mistakenly claiming that the center-left could win if only it were not divided into so many different parties. I want to use this claim as a foil, and illustrate why it is so mistaken.

Basically, the reason there are so many parties in Israel is two-fold: there are real socio-political divisions and there is a quite extreme proportional-representation system. Because of the high proportionality, divisions within a potential governing bloc are quite unlikely to be the reason such a bloc fails ultimately to end up in government. (Yes, there is a moderately high threshold that can cause some wasting of votes. We will come back to that.) A government needs to command the votes of one more than half the Knesset (61 of 120); no party will win a majority (none ever has), and so the process of forming a government is one of post-electoral bargaining. Whoever can get 61 votes in the Knesset (assembly) forms the government. A minority government–tolerated by some Knesset parties that don’t have a formal governing role–is theoretically possible, as it almost always is in a parliamentary democracy, but highly unlikely in Israel.

The Economist claimed that Netanyahu could be defeated if only the opposition would unite. The premise is based on two observations; they are true as far as they go, but that is not very far. First,

Under Mr Netanyahu, Likud has never received more than a quarter of the national vote. Yet it has dominated Israeli politics with the help of smaller nationalist and religious parties.

Second,

Were [opposition parties] running as one they would probably gather 40% of the vote, overtaking Likud.

The idea of a united center-left overtaking Likud is plausible, although 40% could be a stretch. Based on the aggregation of recent polls, all the opposition parties, not including Yisrael Beiteinu and the Joint List, come to an estimated 45.5 seats, which would be about 38%. So if all those parties formed one alliance list, they might get close to 40%. Moreover, is not out of the question that Yisrael Beiteinu (YB), which left the government in November, could join a center-left coalition. Even if they get to 40%, however, getting to the 61 seats needed for a majority remains a stretch. For one thing, it is virtually impossible to construct coalition scenarios around the Joint List being in. (The reasons why would be a topic for another thread; the short version is they would not accept if invited to join a governing coalition, which they won’t be.)

The problem is that this 38% or 40% might still not be enough, absent either a polling shift (or substantial error) in their favor or the defection of some party from the current bloc of governing parties, other than YB. If the Haredi (ultra-orthodox) parties joined them in government, that would be another 11.7 seats on the current polling estimate. So if we take the current opposition (minus Joint List), and add in YB and the two Haredi parties, we are at 45.5 + 4.5 + 11.7. Look, we made it to 61.7! A very bare majority, if the polls are spot-on. But not so fast.

While the Haredi parties have governed with left parties before, the broad center-left alliance the Economist is imagining includes at least one party that would be highly unlikely to go into government with the Haredi parties. Yesh Atid, currently polling at 12.7 seats, has as one of its core reasons for being the diminution of ultra-orthodox religious privileges in society; it successfully kept the Haredi parties out of government when it joined a coalition after the 2013 election. It is hard to imagine it agreeing to sit in a government with the Haredi parties (and vice versa). In fact, one of the reasons for the election being called when it was is that the government–again–failed to resolve the Haredi military draft issue, as required by the Supreme Court. It would not be any easier for a center-left-religious coalition to handle. Such a coalition could also be a problem for Meretz, which is a highly secular, left-wing party. YB, which gets most of its votes from the Russian community, is also closer to Yesh Atid on these issues, because of the official rabbinate’s rejection of many Russian immigrants’ Jewish status, although it has sat in nationalist-religious coalitions before, obviously.

Thus we see here already a reason why the Economist’s explanation for why the left won’t unite into a single alliance–“But none of the party leaders is prepared to serve as number two”–is insufficient. The opposition contains not only differences over who should be its leader, but also real divisions over what should be the course of action of the next government. A lot of the divisions may be personalities, but by no means all of them.

Nonetheless, let’s take the claim at face value. Let’s assume that there is an opposition alliance that, upon uniting, somehow not only does not lose any substantial share of its current voters because of pre-election compromises it has to make, but also is able to attract some voters from the right. It ends up with 48 seats (40%), while Likud has only 30 (25%). Is the most likely government–even with such a board alternative pre-electoral coalition able to start bargaining with the other parties–still one led by Likud? Yes, probably.

While it seems somewhat implausible that a pre-election alliance with 40% would be kept out of power if it was really 15 percentage points ahead of the largest list on the other side, any scenarios that have the center-left forming the next government have to get over the parliamentary arithmetic and real political issues mentioned already before they should be taken seriously.

Moreover, it is not as if the divisions on one side are occurring in a vacuum in which the other side does not exist or know what is happening. If, somehow, the center-left united and was polling at 40%, the right surely would respond with alliance-making of its own. While the various personalities in the smaller right-wing parties and in Likud clearly have a fair amount of contempt for one another, they arguably have fewer unbridgeable policy divisions than the center-left. In other words, if they were faced by a genuine threat of a united center-left, they’d almost certainly construct a more united right. We have seen it before: Likud and Yisrael Beiteinu put together a pre-election alliance in 2013, in part out of concern that Yesh Atid might surpass Likud in seats. While there is no procedural advantage to the largest party or list (just ask Tzipi Livni about the 2009 result), there is nonetheless political value in being first, or at least in not too far behind. Already, there are rumors that Likud and current center-right partner Kulanu may be negotiating a joint slate. (On current polling, that would combine for 34.3 seats, or just under 30%.)

Nonetheless, the bottom line is that, regardless of which list gets the most votes and seats, the government will be the one that can assemble a coalition consisting of at least 61 seats. And the simple fact is that advantage in votes falls to the broad right, not the left. There is no sense in which the divisions on the left are preventing it from winning. This is a proportional system, and so divisions are not costing any potential bloc seats, as they would in a majoritarian system.

But, hold on, what about that threshold? Is it possible that the left could deprive itself of seats because some of its parties fall below the threshold? If that happens, then it does indeed waste votes and potentially displace some seats to the right. So, yes, it is possible. The threshold is 3.25%, and at least one party on the center-left is below that (Livni’s HaTenua). However, Livni clearly is going to take part in some new alliance, now that she has been booted in an especially insulting fashion out of the Zionist Union that she formed with Labor before the 2015 election. Besides, this was not a claim the Economist piece made; it does not even mention the threshold.

One new party that has entered, Gesher (headed by current MK and YB-defector Orly Levy-Abekasis) is perilously close to the threshold. However, it is rather likely it will end up joining some pre-electoral bloc. There is also the newly registered party, Telem, of former Defense Minister Moshe Ya’alon, who has declared he will not sit in a coalition with Netanyahu. Lists, including any alliances, need not be finalized till late February. (And, yes, this will be a general election in more ways than one.)

Moreover, it is not only the left that has to worry about the threshold. Netanyahu was sufficiently worried to propose lowering the threshold before the election. This was after the Knesset had passed the bill to set the election and “disperse” itself, but before the split in one of his current nationalist governing partners, Bayit Yehudi. The effort on the threshold failed, but it shows that it is not just the opposition that has divisions that could cost it.

The remnant of Bayit Yehudi is currently below the threshold. With 2.8 seats, it is about 1.2 short (the 3.25% threshold means usually the minimum size of a party in the Knesset will be 4 seats). It will probably align with one or more other very minor ultranationalist parties, but even in such an alliance, it could still be left out.

The defectors from Bayit Yehudi, Naftali Bennett and Ayelet Shaked, have formed a party to be called New Right. It is currently on 8.8 seats. It will seek to cement the Judea & Samaria settler vote and others opposed to any territorial concessions (helped by recruiting Caroline Glick to the list); it will remain a natural partner for Likud even as it seeks to differentiate itself both from Likud and from Bayit Yehudi. Yet even without the remnant of Bait Yehudi passing the threshold, the current coalition partners are at about 59 seats. So now we are up against one other critical fact of the Israeli party system: there are various parties on the center-left that would be willing to join a Likud-led government. In fact, of all the parties on the center-left (not counting the Joint List, which will not be in any government), the only one I am sure would not join Likud is Meretz, and if we take Ya’alon at his word, whatever list he is on won’t back Netanyahu. (As mentioned before, it is also hard to see Yesh Atid in a government with the Haredi parties, but the party has been in a Likud-led coalition before.)

It just very hard to see a realistic scenario for a non-Likud government, absent a major shift in public preferences. Note that I have not even mentioned yet the legal troubles facing Netanyahu. Could that lead to a shift towards the center-left? Maybe. But don’t count on it. More likely, were the PM to be faced with charges before the election, he’d lose some votes to New Right. In fact, that could even be one of the reasons Bennett and Shaked made their move: their new party and its emerging platform could appeal broadly on the right in a way that the hardline orthodox religious (but not Haredi) components of Bayit Yehudi never would have.

To summarize, divisions on the left (or right) will not keep a camp from winning its full seat potential. Yes, if a party needed for the bloc to form a coalition majority falls below the threshold, that could displace seats to a rival bloc. However, parties that are at serious risk of not reaching 3.25% are likely to ally with other parties. It does not matter if the entire center-left unites; it still has less support in the public than the nationalist camp, and thus the latter would remain in stronger position to form a government. Moreover, it is not even clear that a united center-left would gain more votes than the separate parties can win, given the real divisions they reflect. To some degree this is true on the right, too (see the 2013 Likud Beitenu case), but the right is more cohesive as a potential (and current) government. Things could change between now and the election, but I would not count on it. Scenarios in which the current opposition will be the next government need a more credible story in their favor than just that the opposition needs to be more united.

Open lists in MMP: An option for BC and the experience in Bavaria

One of the options for electoral reform in British Columbia is mixed-member proportional (MMP) representation. The criteria for the potential system allow for a post-referendum decision (if MMP is approved by voters) on whether the party lists should be open or closed. The guide that was sent to all BC voters shows a mock-up of a ballot that looks like New Zealand’s, with closed lists. However, the provincial premier has stated that, if MMP is adopted, lists will be open.

When it comes to lists, it is my opinion that citizens will elect all of the members of the legislature. They will select names that are representative of their communities.

I remain uncertain about the value of open lists under MMP. Is it worth the extra ballot complexity? What additional gain does one get from having preference votes determine order of election for those winning compensatory seats? The MMP Review in New Zealand after the 2011 referendum (in which voters voted to keep MMP) looked at this question extensively. It came down firmly on the side of keeping lists closed.

Nonetheless, the statement by the premier suggests he believes the system is less likely to be chosen if voters expect the lists to be closed. And, given regional districts on the compensation tier, as explicitly called for in the system proposal, the lists would not be too long and thus the ballots not too complex.

It happens that there is one MMP system in existence in which the lists are open. Such a system has been used in Bavaria for quite some time. I actually proposed such a model in a post way back in 2005, quite early in the life of this blog. At the time I had no idea that what I had “invented” was, more or less, the existing Bavarian model.

Of course, Bavaria just had an election. In the thread on that election, Wilf Day offered some valuable insights into how the open lists worked. I am “promoting” selections from Wilf’s comments here. Indented text in the remainder of this post is by Wilf.

The Bavarian lists are fully “open,” and the ballot position has no bearing on the outcome, except to the extent the voters are guided by it, especially seen in voting for the number 1 candidate.

Of the 114 list seats, 31 were elected thanks to voters moving them up the list, while 83 would have been elected with closed lists.

Did the first on the list always get elected? Almost. In the region of Lower Bavaria, the liberal FDP elected only 1 MLA, and he had been second on their regional list.

Did the open lists hurt women? I did not check most results, but the SPD zippers their lists, and I noticed in Upper Palatinate the SPD elected 2 MLAs, list numbers 1 and 3 (two women). Conversely, in Middle Franconia the SPD elected 4 MLAs: 1, 2, 3, and 5 (three men).

Little known fact: a substantial number of voters in Bavaria, being used to voting in federal elections where their second vote is just for a party, blink at the Bavarian ballot, look for the usual space to vote beside the party name, it’s not there, so they put an X beside the party name anyway. A spoiled ballot? No, they count it as a vote for the party. Not a vote for the list as ranked, it does not count for the ranking or for any candidate, but it does count in the party count. Just like Brazil, where a vote for the party is not a vote for the list ranking, except Bavaria does not publicize the option of voting for the party.

Among the more interesting new Free Voter MLAs:

Anna Stolz, lawyer, Mayor of the City of Arnstein; she had been elected Mayor in 2014 as the joint candidate of the Greens, SPD, and Free Voters; the local Greens said they were very proud of her as Mayor. The Free Voter delegates meeting made her number 5 on the state list, but the voters moved her up to second place as one of the two Free Voter MLAs from Lower Franconia.

From Upper Bavaria, the capital region, list #12 was Hans Friedl, with his own platform: “a socially ecologically liberal voice, an immigration law based on the Canadian model, no privatization of the drinking water supply, a clear rejection of the privatization of motorways”). The voters moved him up to #8, making him the last of 8 Free Voters elected in that region.

Note: the comments are excerpted, and the order of ideas is a little different from where they appear in the thread. I thank WIlf for his comments, and for his permission to make them more prominent.

Brazil’s open list is (a little bit of) a hybrid now

Brazil is a classic case of open-list proportional representation (OLPR): lists win seats in proportion to their collective votes in a district (state), but candidates within the list are ordered solely according to preference votes obtained as individuals. These rules can result in individual candidates elected with very small preference-vote totals.

For the most recent Brazilian election, a new provision has gone into force. There is now a threshold on preference votes that candidates must obtain to be elected. This means that, in a very technical sense, a hybrid element has been brought into the Brazilian system. However, the provision is not the usual hybrid seen in “preferential list” systems, whereby seats not filled on preference votes are filled instead according to a party’s (or coalition’s) pre-determined rank. That hybrid format is what is typically called a flexible list or a semi-open list. However, Brazilian lists remain unranked, except via the preference votes.

Rather, in Brazil, a list that has an insufficient number of candidates with above-threshold preference votes forfeits those seats to other lists in the district. The threshold is set at 10% of the electoral quota, which is a Hare quota (1/M, where M is district magnitude).

This provision changed the allocation of 8 seats. Given a Chamber of Deputies with over 500 seats, we should not exaggerate the significance of the change, although of course, some other parties might have adjusted either their nomination behavior or their “intra-party vote management” practices (defined below) to avoid being hit by the threshold.

The Chamber’s website has an article regarding the seat shifts, and a table with the details (in Portuguese). The PSL, which is the party of the likely next president, Jairo Bolsonaro, won 7 fewer seats than it would have without the threshold. All these seats were in São Paulo, which is the highest-magnitude district in Brazil (M=70). The threshold there is thus 0.143% of the votes cast in the state. The Novo list in Rio Grande do Sul (M=31) also lost 1 seat due to the intra-list threshold. (Novo, meaning “New”, is a small liberal party.)

In São Paulo, the seven PSL candidates who were not eligible to take seats the list otherwise would have won had vote totals ranging from 19,731 to 25,908. They were replaced by candidates on six different lists with preference votes ranging from 56,033 to 92,257, suggesting the replacements had, on average, about three times the votes of the forfeiting candidates. (The party that picked up two of these seats was the Democrats.) In Rio Grande do Sul, the seat Novo forfeited would have been won by a candidate with 11,003 votes, but was instead filled by a candidate the Brazilian Labor Party (PTB, not to be confused with the PT of Lula) who had 69,904 votes, a preference-vote total 6.35 times greater than that of the forfeiting candidate.

As is clear from the vote totals of those who lost under this provision and those who gained, if the intention was to prevent candidates with marginal personal followings from riding in on the “coattails” of strong list-pullers (whose popularity increases the votes of the collective list), then the reformers can declare “mission accomplished”.

I am personally quite excited by this provision, which I had missed when summarizing minor changes made to the electoral law in 2017, because I once wrote up a proposal for just such a hybrid. It is in some text that was going to be part of one of the chapters in Votes from Seats, but Rein Taagepera and I decided it was not directly germane to the book and left it out. The chapter it would have been part of compares OLPR to the single non-transferable vote (SNTV) with respect to vote shares of first and last winners, and regarding the extent to which parties do (or do not) manage their intra-party competition.

Managing intra-party competition refers to parties doing one or both of: (1) restricting the number of candidates nominated, or (2) intervening in the campaign in an effort to shift votes from non-viable candidates to viable ones.

Under SNTV, these intra-party competition-management practices are critical because the total number of seats a party (or set of cooperating parties) can elect is entirely dependent on how many individual candidates it has whose votes are in the top-M vote totals in the district. Under OLPR, parties have no incentive to do this, if their goal is simply to maximize list seats–a list under OLPR can never displace seats to another list due to having “too many” candidates or having the candidates’ vote totals be widely unequal. (Parties may have other reasons to care about which candidates win, and multiple parties running in alliance face an SNTV-like conundrum in that they are competing with one another inside the list to get their candidates into the top s, where s is the number of seats won by the list. But these are separate problems, and the latter is a problem covered in Votes from Seats).

The proposal I drafted was a hybrid of OLPR and SNTV (unlike flexible lists, which re a hybrid of OLPR and closed-list PR). A threshold would be set on preference votes, and if a list won more seats, via application of the inter-list allocation rule, than it had candidates over the threshold, it would forfeit these seats. Any such forfeited seats would go into an “SNTV pool” to be be won by the otherwise unelected candidates with the highest preference-vote totals, independent of which list they had run on. My intention in devising this proposal was to encourage parties to be more active in managing their intra-party competition–taking some aspects of SNTV as beneficial–in order to make victory by candidates with marginal personal popularity less likely. (I would have set the threshold a little higher than 10% of a Hare quota.)

The article on the Chamber website is not clear on the precise rule now used in Brazil for deciding on the replacement candidates. In any case, it certainly has a similar effect to my proposal. (From a comment by Manuel at the earlier thread, it seems the forfeited seats are assigned proportionally rather than SNTV-like.) I can’t claim credit, as there is no way any Brazilian official saw my unpublished proposal. But I am pleased that some such a provision has been adopted somewhere.

Thanks to Dr. Kristin Wylie (on Twitter) for calling my attention to this article.

Lebanon, welcome to open alliance lists!

Lebanon’s election is coming up (6 May), and the country is getting its first look at a new open-list proportional electoral system (profiled previously here by Amal Hamdan).

An interesting blog post from 12 March by Gino Raidy has just come to my attention*: “Why Political Parties are Terrified of Forming Lists”. The author discusses the perils for parties joining on an alliance list. Because the lists are open, it is possible for one party to help boost its partner’s seats but elect none of its own candidates. On the other hand, it is also possible that parties (and alliances) will want to recruit relatively independent figures who can appeal to a wider electorate.

These sorts of issues may be new to Lebanon, but they will be familiar to readers of this blog. I have talked about them before, most recently in a discussion of Brazil and Finland, where open alliance lists have been in place for some time.

El Salvador ballots

Thanks to the really wonderful Twitter feed of La Prensa Grafica, following are some photos of voted ballots from El Salvador’s assembly elections of 4 March.

The ballot format is “free list” under which it is a party-list proportional-representation system, but unlike other types of list, the voter can give preference votes to candidates nominated on different lists (a feature sometimes known as panachage).

Here is one that is marked for candidates in several different lists, but none in the government-supporting parties, FMLN (red) and GANA (orange).

Here is one that marked all of the candidates in the ARENA party.

That’s a lot of work! A voter who wants to vote a straight ticket can simply put an X over the party symbol at the top, and it counts the same as a vote for each candidate on the list.

Now here is one whose vote will count for no one, but the voter had fun making statements.

Under the free-list system, a party’s votes is the sum of all the preference votes its candidates receive (including the label votes counted as one for each candidate on the list). Any preference vote thus contributes to the list’s pooled vote total for purposes of calculating seats per list. If a voter does not cast all M votes (where M is the district magnitude), that voter is sacrificing a percentage of his or her entitled voting weight.

This process also means that calculating national party vote totals is not straightforward. I am not sure what method of weighting votes across the varying-magnitude districts is used in El Salvador’s official reporting of national totals.

Honduras 2017

Honduras has presidential and congressional elections today. I know essentially  nothing about the elections except: (1) There is widespread fear they will not be fair, and (2) The congress is elected by free-list PR.

It is for the latter reason that I share the following image, which I found on Twitter, posted by Pablo Secchi.

The ballot is similar to that in neighboring El Salvador, which also uses a free list. The voter may cast up to M votes, where M is the district magnitude (number of seats elected from the district). The votes may be cast without regard for party, but each candidate vote is also a vote for the list on which the candidate was nominated. Thus it is a party-list PR system, but one in which voters are free to spread their support across multiple parties. It also means that voters are weighted differently, according to whether they cast all their votes or not.

It appears that voters can simply cast a list vote. I believe that doing so is equivalent to casting votes for as many candidates as are nominated on that list (presumably always M).

Parties and personal-vote earning attributes in OLPR

In the forthcoming Votes from Seats, Rein Taagepera and I build on the earlier argument of Bergman, Shugart, and Watt (Electoral Studies, 2013) about incentives of political parties to “manage” the competition among their candidates under various intra-party allocation rules. The short version of the story is that parties under open-list PR should be willing to tolerate “laissez faire” competition, because no excess in the number of candidates nor imbalance in the candidates’ votes can affect the party’s ability to convert its collective vote total into a proportional share of the seats (within the limits of the district magnitude and inter-party allocation formula).

The claim about laissez faire competition under OLPR rests on the assumption that parties are only interested in seat-maximization, and not in the precise set of candidates who win. It also rests on the assumption that “party” and “list” are the same thing.

The second assumption is already relaxed in Votes from Seats, where we devote almost an entire chapter to the topic of how alliance lists work, focusing on the cases of Brazil, Chile, and Finland. In these systems (and some others) many lists contain candidates of two or more parties. In that case, the parties on the list are in direct competition with one another for a share of the seats won by the list as a whole. Thus parties would need to manage their vote–i.e., concern themselves with the distribution of votes across their candidates.

The first assumption–regarding parties’ indifference about their personnel–is not something we actually believe is true in practice. Science involves making simplifications, and we show in the book that using this simplifying assumption is quite powerful in predicting, via deductive logic, the average patterns in the preference vote shares of candidates (i.e., candidate votes divided by total list votes in a district). So, for the purposes of the book (and the earlier article), the strict assumption of indifference worked to get us a step farther down the road to understanding how electoral systems shape candidate vote shares.

In earlier drafts of the book, we worked on attempts to analyze how parties might affect the election of specific candidates, even though they lack ranking control, through nominations. We took these sections out because we were unable to come up with a deductive model of the process–a key methodological criterion around which the book is based. In the remainder of this entry, I will post and discuss two graphs that we took out of the book but that demonstrate the (still underdeveloped) idea of parties’ engaging in forms of intraparty management–even under OLPR.

The immediate reason for returning to think about this now was the recent American Political Science Association annual meeting, at which I presented a paper with Åsa von Schoultz that incorporates both the logical models of preference-vote distribution and the personal vote-earning attributes (PVEAs) of the candidates themselves. On the same panel was a fascinating paper by José Antonio Cheibub and Gisela Sin, which (among other things) analyzed the discontinuity in ratios of one candidate’s votes to the next candidate’s when they are sorted in descending order by preference votes. They find that, in Brazil, there is a tendency for these ratios to be greater at “last winner to first loser” and at “first loser to second loser” than among winners higher up or losers lower down.

A pattern like that found by Cheibub and Sin would not be found if there were not some “coordination” going on. Such coordination could be done by voters or by interest groups or others with a desire to see certain candidates elected over others. Or it could be done by parties. If by parties, it would be a form of intra-party management. For instance, parties could achieve a desired concentration of votes on the eventually elected candidates by ensuring a mix of candidates appealing to different groups of voters, or through allocating campaign resources, or some mix of these and other tactics.

One way to manage the vote would be through exploiting the party’s knowledge of the relative appeals of specific candidates or types of candidates. If the party had perfect information, it could renominate just the right number of incumbents and nominate the right number of local council members, or other politicians with popular appeal and whom the party sees as promising future legislative personnel. In other words, through nominating candidates with given PVEAs it could structure the balance of different traits and constituencies represented within its delegation.

The following data plots from Brazil and Finland point towards how such PVEA management might work.

 

The plots show the share of candidates at any given relative rank (list position/seats won) who have a given PVEA: incumbent assembly (national) member or local council. The local regression (lowess) curves plot the pattern, and in the case of Brazil, I also plot a lowess for the state assembly members running on the deputies list (but not the data points, because of the clutter). The incumbent MP curves for the two countries are nearly identical, with relatively few MPs losing and more near the top preference vote totals.

The local candidates’ curves also have a similar shape—rising near the bottom of the electable ranks on the list and then still rising among the top losers, before plummeting. The obvious difference is that there are a lot more locals in Finland than in Brazil. The curve for Brazilian state legislators running for federal deputy looks like a much-flattened version of the incumbent deputies’ curve.

These plots may be showing that parties are indeed managing the distribution of votes across candidates. They are doing so by whom they nominate. They probably have pretty good information about the vote-earning potential of various candidates, and they can “clear a path” for the candidates they consider sufficiently valuable by not putting too many similarly strong candidates on the list against them. Obviously, what I have shown here does not prove that point, but it is suggestive of how parties might “coordinate” on the intraparty dimension, through managing the types of candidates they select.

A possible objection is that parties could not possibly know the votes that a candidate could bring to the list. After all, these lists–especially in high magnitude districts–are so competitive! Another graph suggests it might not be so hard for parties after all, at least when nominating candidates who have run before for some office.

 

Do parties have good information about the votes a candidate will obtain? Evidently so. This graph compares 2002 votes of Brazilian candidates to 1998 votes, whether their 1998 campaign was as a deputy candidate or a state legislative candidate. The diagonal is the equality line; a regression is not much different from it. In other words, a candidate’s votes in the prior election are a pretty strong predictor of the candidate’s votes in the current election (at least in Brazil, 1998-2002). This is generally true for those who won their contest the previous election and those who had small vote totals. And it applies to state legislative candidates even though they are running in different-magnitude districts. (The legislators of a given state are elected in a single statewide district, just as the national deputies are elected in state districts, but the magnitudes are greater for the state legislature.)

Parties amaze sometimes at how good they are with this stuff!

Certainly, when I see things like this I realize that all the old ideas about chaotic competition in OLPR or parties lacking control just do not stand up.

So, yes, parties can tolerate laissez faire competition among the candidates on their list–provided they are interested only in maximizing the list’s seat total. And assuming that this is all they care about allows us to understand average patterns of vote distribution. A key goal is to introduce other variables–notably PVEAs–to understand how individual candidates deviate from these logically predicted (and empirically confirmed) averages. That was the point of the von Schoultz-Shugart APSA paper, focused on Finland. The next step is to try to understand PVEAs and prior vote totals as a window on how parties manage the vote, even under OLPR.
