Mexico, 2018

Mexico has its elections for President, Chamber of Deputies, and Senate on 1 July. It has been clear for a while that, barring a big surprise, Andrés Manuel López Obrador (popularly known as AMLO) will win.

AMLO’s support has risen steadily out of what looked like a tight three-way contest some months ago into a strong lead. When voters responding “no preference” are removed, it even looks likely that AMLO could win a clear majority of votes. Mexico elects its presidency via nationwide plurality, and no Mexican president has earned half the votes since 1994 (at a time when most experts still considered the regime authoritarian, albeit increasingly competitive).

Assuming AMLO wins, it will highlight the competitive three-party nature of the system. When the center-right National Action Party (PAN) won the presidency in 2000, it broke decades of continuous control by the Institutional Revolutionary Party (PRI). The PAN won again in 2006, on less than 37% of the votes in a very tight race, with AMLO close behind (and refusing to acknowledge defeat). The PRI returned to the presidency in 2012, and now AMLO will give the left its chance. (AMLO was with the Party of the Democratic Revolution, PRD, but in recent years has set up a new party, MORENA, while the remnant PRD is backing the PAN candidate this time.)

I would be very interested in seeing an analysis of AMLO’s own manifesto (and his party’s, if separate). There is much hand-wringing over his leftist “populism”. However, when he ran in 2006, he staked out a centrist economic platform well to the right of his own party–a clear case of what “presidentialization” does to parties. (See the discussion of the general point, and also the 2006 Mexican campaign, in my book with David Samuels, Presidents, Parties, and Prime Ministers). Is he doing so this time? I can’t claim to have followed closely enough to know.

As for the Chamber of Deputies, if the pattern of recent Mexican elections holds, the party winning the presidency will win fewer votes for its congressional candidates. That could mean MORENA (and pre-election allies) will not have a majority of seats. On the other hand, as noted above, these previous presidents have not themselves won majorities. Moreover, the electoral system is mixed-member (with the voter having a single vote). It is sometimes erroneously categorized as mixed-member proportional (MMP), but it is actually leans much more to the majoritarian category (MMM). Seats won based on nationwide votes for party are added to single-seat districts won (by plurality).

The allocation is not compensatory, but it is also not strictly parallel. There are caps on allowable over-representation (unlike in a “pure” MMM system). The most important cap is that no party can have a final seat percentage that is more than eight percentage points above its vote percentage. Thus if a party wins under 42% of the votes, it is unable to have a majority of seats. If it gets over 42% it is not guaranteed a majority, but a majority becomes likely, due to the non-compensatory nature of the allocation. This cap kept the PRI from retaining its majority in the midterm election of 1997, and I believe it has been hit in several subsequent elections, as well. This is what I will be watching most closely: Will MORENA (and allies) get a Deputies majority?

The Senate is also elected in a mix of regional and nationwide seats. Each state has three senators, elected by closed list, limited-nominations plurality. The largest list gets two seats and the runner up gets one. Then there are 32 seats elected by nationwide proportional representation (allocated in parallel, not compensatory manner).

These provisions, combined with the regionalization of party support in Mexico, make it difficult for a party (or alliance) to win a majority of the Senate’s 128 seats. AMLO is unlikely to have majorities in both houses, but it is worth noting that the federal budget must clear only the Chamber. There is no Senate veto on the spending side of the budget, although both houses must pass all other types of bills. Thus the left will be in a strong, but not unchecked, position to implement its program for the first time in Mexican democratic history.

Costa Rica runoff, 2018: Alvarado (the better one) wins

In Costa Rica’s runoff, Carlos Alvarado beat Fabricio Alvarado. That is a relief. Fabricio ran his campaign mostly around stifling gay rights, and polling had the race very close. In fact, most polls had FA ahead (see the poll summaries at Wikipedia). However, at 60.6% to 39.3% for CA, it was not close at all.

This runoff followed an extraordinarily fragmented first round, in which four candidates had votes between 15% and 25%. FA led the first round, with 24.99% to CA’s 21.63%. The candidates of the two older parties (PLN and Social Christian Unity) came in third and fourth.

Costa Rica’s rules since the current regime was founded in 1949 have required a runoff among the top two candidates if the leader did not clear 40% of the vote in the first round. Because of the country’s historic two-party system (with some additional trailing parties), a runoff was never required until 2002. The party system has changed dramatically in recent cycles. A runoff was narrowly averted in 2006 (winner with 40.9%), and was next required in 2014 (leader with 30.6%, and runner-up with 29.7%, although the runoff contender, from the PLN, quit the race), and now in 2018.

Carlos Alvarado was nominated by the party of the incumbent president (Luís Guillermo Solís), the Citizens’ Action Party. This party has established itself as a major party in that it has passed the test of electing not one, but now two, different presidential nominees. Moreover, it has finished ahead of both of the old parties in two consecutive first rounds and ahead of at least one of them in four straight elections.

The runner-up candidate’s party, on the other hand, is a newer one. The National Restoration Party was contesting only its second presidential election (though it won congressional seats in 2006), and in 2014 its candidate managed under 1.4% of the vote.

The now more fragmented political scene raises the obvious question of how President-elect Carlos Alvarado will be able to govern. The Costa Rican presidency is one of the weaker ones among pure presidential democracies, and as the congress was elected concurrently with the first round, reflects that round’s fragmentation.

The president-elect’s party, Citizens’ Action, has only the third highest seat total in the Legislative Assembly. It won 16.3% of votes and 10 of the 57 seats (17.5%). The leading party will be the old PLN, which won 19.5% of the votes (compared to 18.6% for its presidential candidate) and 17 seats (29.9%). The National Restoration Party finished second (as it did in the presidential first round) with just over 18% of the votes and 14 of the 57 seats (24.6%).  The Social Christian Unity Party won 14.6% and 9 seats. No other party has more than 4 seats, and the total number of parties represented is seven.

Notably, even if he strikes a deal with the PLN, the president will not have quite enough to control the assembly: such a coalition would be two seats short.

The Libertarian Movement–one of the few relatively well established parties anywhere of this family–slipped well back. It will be without seats for the first time since before 1998. (The party won 9 seats in 2010, when its presidential candidate finished third with 20.8% of the vote.)

The election results will pose a governing challenge, but at least the requirement for a second round has led to the better Alvarado being elected.

Emerging signs of clarity in Colombian presidential contest?

Colombia Report notes that the leading center-right candidate for the presidency, Ivan Duque, has surged dramatically, according to a recent poll. The main candidate of the left, Gustavo Petro, also has surged, albeit less dramatically.

The article indicates that:

The poll was the first since legislative elections that were held on March 11.

As I noted before those elections, that is what counter-honeymoon congressional elections do: clarify the field. It’s also why they tend to be so highly fragmented, with parties associated with many potential presidential candidates running to show their strength in advance of the actual presidential contest.

The surges by Duque and Petro come on the heels of their victories in presidential nominating primaries held at the same time as the congressional elections.

The Colombian presidential election is held in two rounds if (as is expected to be the case) no one wins over half the votes in the first round. If this poll is capturing a trend, rather than an outlier, there may not be much drama in who the top two will be, but the runoff campaign would be critical to consolidating support from the many also-rans. The poll in question has Duque at 40%, and runner-up Petro at only 24%. The third candidate, Sergio Fajardo, is way back, under 10%.

It is possible that the surges of Duque and Petro are temporary boosts from the primaries, and that the one or two of the other candidates–who did not run in primaries–will recover. On the other hand, it is just as possible that running in (and winning!) a primary is a smashingly good way to advertise your presidential campaign.

Colombia 2018: Counter-honeymoon elections and presidential primaries

Colombians have voted today in elections for the two chambers of the congress and in (optional) presidential primaries. I believe Colombia is the only country to hold assembly and presidential-primary elections on the same day. Notably, these are the first elections in which the political party formed by the former guerrilla movement, FARC, is participating.

Colombia is rare among presidential (or semi-presidential) democracies in using counter-honeymoon elections over a long time frame. A counter-honeymoon election is one held late in the presidential term, much closer to the next presidential election.

In fact, I believe that since 1958, only three Colombian congressional elections have not been in the counter-honeymoon: 1970 and 1974 (which were concurrent) and 1991 (which was an early election called by the Constituent Assembly that had been elected the preceding year to create a new constitution).

By the measure of elapsed time between presidential elections, Colombia is about as extreme as can be. The elapsed time of its recent elections, including today’s, has been around 0.95. In other words, when the congress is elected, only 5% of the time between presidential elections remains.

Among all elections from presidential systems in the dataset used for Votes from Seats, the mean elapsed time is 0.268. However, most assembly elections in the wider world of presidential democracies are concurrent. If we eliminate these from the sample, the mean is 0.540. In other words, on average, non-concurrent elections tend to be held around the midterm. But the range is large. The minimum is 0.164 (France 1988; the 2017 honeymoon election France also had a similar value). The maximum is 0.992 (Poland 2005; another near the maximum was El Salvador 2009).

When an election is this late in a presidential term it is likely to be essentially a preliminary round of competition for the upcoming presidential election. I wrote about this effect in Colombia in 2010. That would be the expected effect even if there were no presidential candidates on the ballot, but in Colombia, there are. Parties that choose to hold a presidential primary (consulta) hold them on the same date as the congressional elections. The first such primary was held by the Liberal Party at the same time as the 1990 congressional elections. And most congressional elections since then have featured one or more primaries.

There were two primaries in Colombia today. They were not actually party primaries, but something new for Colombia (and rare anywhere): alliance primaries. There is a right-wing alliance holding a primary among three candidates, including those of the Democratic Center (the party led by former President Alvaro Uribe and strongly opposed to the peace terms the FARC received) and the Conservative Party. Then there is a left-wing alliance holding a primary among two candidates. In addition, there are other parties that already have nominated candidates for the upcoming first round of the presidential contest itself, and thus are not holding primaries. The primaries are “open” in the sense that any voter may request either one of the primary ballots. (See details at AS-COA.)

According to data graphed and analyzed statistically in Votes from Seats, counter-honeymoon elections tend to be more fragmented than those at other points in the term. The Seat Product Model, predicting the effective number of parties (both seat-winning and vote-earning) tends to be quite accurate for assemblies in presidential democracies* except when held with an elapsed time greater than roughly 0.90. Really late-term elections have a tendency to an effective number of parties significantly higher than the Seat Product Model prediction (depicted in Figure 12.1 in the book).

We suspect that is precisely because with the current president’s term almost up, and politicians jockeying for position in the next presidential election, more parties enter and receive votes as a sort of “testing of the waters” prior to the presidential election.

Would holding presidential primaries on the same day dampen this fragmenting effect of the counter-honeymoon? I see no reason why it would. It simply inflates the number of presidential candidates (or “pre-candidates”) testing the waters. Moreover, if the primary is for an alliance, rather than a single party–as is the case in Colombia this year–then the parties have every incentive to run separately and seek to boost their legislative vote as well as their preferred candidate for the presidency.

Thus Colombia’s high fragmentation in recent elections might be explained both by the counter-honeymoon assembly election and the primaries. Moreover, the presidential election itself is a two-round process, and the Senate is a single nationwide district (M=100). That is a lot of things pointing towards a high number of parties!

As for the FARC’s electoral debut, how many seats will it win? I will predict five in each house.***

** This is one of the easier predictions I will ever make. This is what the peace accord guarantees them. They could win more, if they won sufficient votes to elect more. That is highly unlikely.

The Salvadoran result 2018: The electoral cycle counts!

[Note: the following has been revised based on updated voting results– 9 March, 17:17 PM PST]

Before the assembly election in El Salvador, I suggested that the FMLN should be expected to win 24.2% of the vote. I hedged, saying I thought the Salvadoran party system probably was still too rigid to allow one of its two leading parties to fall off that far. I should not have hedged, because the preliminary results show that the largest party will be the opposition ARENA, which won 42.3%. The FMLN got 24.4%. How about that. I was off by a tenth of a percentage point in my pre-election prediction!

Well, as nice as that would be as a story, it is more complicated than that…

now realize that I made an error in calculating my expectation of 24.2%. I based the expectation on the fact that the FMLN is the party of the incumbent president, that this election was being held with 80% of the president’s inter-electoral time lapsed, and the president’s own (first-round) vote total (in 2013). It was in the latter factor that I made a mistake, using 39.0%; that was the ARENA total, but the FMLN candidate, Salvador Sánchez Cerén, had 48.9%. Plugging that into the formula (shown below), I should have “expected” the FMLN to get 30.3% of the vote in this past Sunday’s assembly election. So the party actually did a good deal worse than the corrected expectation. And I did worse in my prediction.

Perhaps the party system is no longer so rigid; one of the leading parties can fall below a quarter of the votes after all. Alternatively, as I shall explore here, perhaps I made a second countervailing mistake, which was not to include a coalition partner. If we add the votes of GANA, a center-right party but one that has supported FMLN presidencies since 2010 and, importantly, did not compete against Sánchez Cerén in the presidential contest, we get 35.9%. That’s greater that my (corrected) expectation of 30.3%, but somewhat closer to it than the FMLN’s own vote. I will return to this issue of party vs. alliance later.

The FMLN’s 24.4% is its worst showing in the votes for assembly since its debut election in 1994 (21.4%); that election was concurrent with the presidential election and the party ran just behind its presidential candidate (24.9%) who was a very distant second. Since then, the party has won 33.0%, 35.2%, 34.0%, 39.7%, 42.6%, 36.8%, 37.2%, and now 24.4%.

The party’s high-water mark was 2009, the “counter-honeymoon” election that presaged the leftist, ex-guerrila, party’s first presidential win a few months later.* Then, holding the presidency, it slipped in 2012, an election held with about 60% of the president’s term elapsed. In 2014, it won the presidency again, then held its own in the 2015 election, held with 20% of the new president’s term elapsed.

GANA first appeared, as a split from ARENA, in 2010, just under a year after the election of the first FMLN president. It has now run in three assembly elections staring with 2012, and its votes have been 9.6%, 9.2%, and 11.5%. Interestingly, it gained in 2018 even while the FMLN lost badly. If we add the two parties’ votes together for the last three elections, we get 46.4% (not much less than Sánchez Cerén’s own percentage in 2014), 46.4% (yes, again) in 2015, and 35.9%. That is obviously a sharp decline in the two parties’ combined votes, even if one of the partners did experience an increase. FMLN and GANA will now will have around 40% of the assembly seats, whereas they held half the seats after both the 2012 and 2015 elections.

What led to the sharp decline this time? Many political factors, no doubt. But what really counts is the elapsed time–an election this late in a presidential term tends to be bad for the presidential party–or alliance. The FMLN in 2018 is just the latest example of an effect I first researched in my dissertation (1988) and published about in the APSR in 1995.

Now, via Votes from Seats, we have a formula:

Rp=1.20–0.725E,

where Rp is the “presidential vote ratio”– vote share of the president’s party in the assembly election, divided by the president’s own vote share (in the first round, if two-round system)–and E is the elapsed time (the number of months into the presidential inter-electoral period in which the assembly election takes place).

The key question around which this post is based is whether we should mean “party” literally as the party of which the president is nominee, or if we should include supporting parties that do not compete against the candidate. If you think it is cheating to use the alliance, I am being transparent and reporting the party totals. If you think it is OK to use the alliance when the two parties in question do not compete against each for presidency and cooperate in the assembly–despite running separately–we can compute the totals that way, too.

The formula above expects Rp=0.620 because E=0.80 for this election. Using only the FMLN assembly vote only, observed Rp=0.244/0.489=0.489. Using the FMLN+GANA vote, observed Rp=0.359/0.489=0.734. With the expected Rp=0.620, we get the previously mentioned expectation of 0.303 for the president’s alliance vote share. Obviously the president’s own vote does not change with these calculations, because any GANA-aligned voters who voted for the FMLN candidate are already included. This is why I think it makes sense to use the combined votes–not only because it makes the formula “work” better. (Honest! But F&V readers get to do peer review here!)**

This is the second nonconcurrent assembly election I have watched closely since Rein Taagepera and I developed the formula for our book (published in October, 2017). The other was in France. In April, 2017, I “predicted” that the brand new party of Emmanuel Macron would win around 29% of the vote. This was the day after the first round, and assuming he would win the second round (which he did, easily). At the time, much media commentary was of a hand-wringing character: Macron would be weak, maybe even face cohabitation, because he didn’t have any party to speak of. I said no, the electoral cycle will ensure he gets a good boost in votes in the assembly election. An elapsed time (E) of 0.017, an extreme “honeymoon” election, would almost guarantee it.

In fact, the election resulted in Macron’s party winning 32% of the vote. (And, a large majority of seats, due to the disproportional electoral system.)

So, that’s two elections in the past year called (more or less) correctly, within a few percentage points, based only on the elapsed time and the president’s own initial vote share.

I still hesitate to call this a prediction, because the parameters in the formula (1.20 and 0.725, above) are not themselves based on deductive logic. And perhaps I also should hesitate because of the ambiguity over party vs. alliance, as discussed in this post. But there just may be something to these electoral cycle effects, after all.

[Note: lightly edited since posting.]

______ Notes
* The 2009 presidential election featured only two candidates. So the party’s presidential vote was inflated due to the abstention of all but the two big parties from the presidential race that year. This is the only time smaller parties have not contested the first round. As I said at the time, the decision by the then-ARENA majority to shift from a concurrent to counter-honeymoon assembly election that year converted the assembly election into a “de-facto first round of the presidential election”. The right got spooked, perhaps, by the strong showing of the FMLN, and did not want to risk a division, even in the two-round election. The left followed suit and, with a sole candidate, narrowly won.


** In the 2015 election, based on the new president’s 48.9% of the (first round) vote in 2014 and elapsed time, E=0.20, we would have expected a votes ratio Rp=1.055. That would mean an assembly vote percentage of 51.6%. The FMLN itself won only 37.2%, but if we include GANA, as noted, we get 46.4% (Rp=0.949), which is a small under-performance. (Consequential, of course, as they failed to get the majority predicted.) How about one election farther back in the cycle? In 2012, GANA existed, but that party had not existed at the time the then-incumbent president of the FMLN was elected. So we certainly can’t include it in the calculation for 2012! For that election E=0.60, and so expected Rp=0.765. The president had won 51.3%, so we’d expect the FMLN to have won 39.2%. It actually won 36.8% (observed Rp=0.719), so it did only a little worse than the formula suggests it could have expected.

 

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.

Salvadoran assembly election, 2018

El Salvador has its nonconcurrent assembly election on 4 March. (Also, municipal elections on the same day.) There are not very many pure presidential systems that have assembly and presidential elections nonconcurrent; this is one of many reasons why El Salvador fascinates me.

Another is the enduring relatively rigid division of the party system between the ex-guerrilla FMLN and the right-wing ARENA parties. Yet another is the free-list (panachage) system adopted in 2015. It makes for pretty big ballots!

El Salvador has presidential elections on a five-year cycle and assembly on a three-year cycle. Since the current regime was established in the early 1980s (in the midst of the civil war), elections have occurred in the same year twice. In 1994 they were concurrent. In 2009, the right-wing bloc in the assembly moved their own election up ahead of the presidential, making for a counter-honeymoon election.

In the most recent assembly election (2015), ARENA won 32 seats to the FMLN’s 31 (the assembly size is 84). In the most recent presidential election (2014), the FMLN candidate, Salvador Sánchez Cerén, won the two-candidate runoff with 50.1%. As I said, it is a closely divided party system! One factor that makes it less rigid than it once was is the emergence of GANA, which split from ARENA after the election of the first FMLN president (Mauricio Funes) in 2009. The emergence of GANA can be seen as an example of “presidentialization” of the party system, in that it was a splinter from the former presidential party to support the new president from the other side of the political divide. GANA remains broadly “conservative” but works with the FMLN in the assembly. It won 11 seats in 2015.

Polls* suggest that ARENA is in the lead. So does the electoral cycle. This election is quite late in the president’s term. The FMLN won 37.2% of the vote in 2015, somewhat down on its first-round presidential vote a year earlier (39.0%). That’s a ratio of assembly to presidential vote of 0.949. The formula presented in Votes from Seats suggests that an assembly election with 20% of the time elapsed between presidential elections would tend, on average, to feature a ratio of 1.055. (See my discussion of the formula and application to France, 2017.) So the party did only very slightly worse than we would expect, based only on a pattern documented from a wide range of elections in presidential systems. This election is at 80% elapsed time between presidential elections, which ought to produce a ratio of 0.620, or a vote of 24.2%. I suspect the Salvadoran party system is still too rigid for the FMLN to fall that far, but anything below 30% would not be a surprise, given the timing of the election. [UPDATE: I used the wrong presidential vote numbers. See comment below.]

As for the free-list electoral system, the voter may cast as many votes as the magnitude of the electoral district (which averages six, but is highly variable according to population). In much of my work, I study the process of “personal votes“; I see now that certain of my assumptions could be called into question: that candidates not only “seek” such votes but that they have consented to being candidates. There actually is an item in the Salvadoran press about a candidate who has asked to be de-listed because she did not consent to being a candidate!

Of course, another question is just how much do candidates campaign for personal votes? Another item from the Salvadoran press, from late December, showed a campaign billboard for a specific candidate.

In this case, the candidate had jumped the gun on the campaign period and was admonished by the electoral authority. So, yes, candidates (at least some) apparently do campaign for personal votes, albeit sometimes too eagerly.

Nonconcurrent elections, a post-civil-war party system, free-list PR. Plus, pupusa contests! El Salvador has a lot to hold my interest!

* The linked article is incorrect on the electoral system. It says that the Salvadoran electoral system has 20 nationwide seats. That was last true for the 2003 election. (The source linked to is from 2013, only a decade after such a system was last used!) There are 84 seats, 14 districts.
