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.

Temperature means, winter months, 2013-18

By popular demand*, here’s a full accounting of our winter temperatures since moving to the current location.

The stats really drive home just what an unusual winter this was, with the colder temperatures very much concentrated towards the latter part. I discussed the consequences of this for the deciduous fruit tree blooms in an earlier “planting“.

February’s mean low was more than four degrees below the five-year mean, and the March high and low were both 3-4 degrees below the five-year means.

December was also colder than normal, in terms of overnight lows although the daytime highs were the warmest experienced in a December thus far. The December cold was not as far below norm as we experienced our first winter here, 2013-14, when an extreme freeze was very costly to some of my citrus and other subtropical trees. Even the Eucs had damage that winter.

* Not really, I must admit.

Sierra Leone 2018

[See caveat in comments about the electoral rules of the earlier elections. For now, I am not changing the post, even though I should re-do it with averages only from the FPTP elections.]

On Sunday, Sierra Leone held its presidential runoff. Sierra Leone is one of those examples of a relatively rare combination: presidentialism with an assembly elected by plurality in single-seat districts. Some of the other examples of this combo are also found in West Africa, including Ghana and Liberia. In this entry, I will consider the effects of Sierra Leone’s institutions on the party system, applying some of the logical models of Votes from Seats.

The runoff rule used for the presidency is even rarer (unique?). A second round is required if the leading candidate in the first round does not reach 55% of the valid votes (Art. 42.2.e of the constitution of 1991).

Julius Maada Bio of the Sierra Leone People’s Party (SLPP) won 43.3% in the first round on 7 March. The runner up was Samura Kamara of the All People’s Congress (APC), with 42.7%. This was the country’s closest contest thus far since the current democratic institutions were inaugurated in 1996.

Sierra Leone has had one president during this time period who was elected with less than 55%. In 2007, Ernest Bai Koroma of the APC won with just 54.62%. However, this was in the runoff. He had 44.3% (to 38.3% for the runner up) in the first round. And herein lies the real oddity: One might wonder why it is OK to elect a president with just half of the votes, plus one, in a two-candidate runoff, but a total falling between 50% (plus one) and (one vote under) 55% would not be sufficient to win in a single round.

So far Sierra Leone has not had an election in which the first-round leader was in that 50-55% grey zone. Dating to 1996, first-round leaders’ vote percentages have been 35.8, 70.1, 44.3, 58.7, and 43.3

Sunday’s runoff (results for which will not be known for about a week) is to replace outgoing President Koroma, who was elected in 2007 and reelected in 2012.

In the assembly elections, concurrent with the first round of the presidential election, only 90 of the 132 constituencies have been declared so far. (There are also 12 seats reserved for tribal chiefs.) The SLPP has won 47 seats to the APS’s 32. The Coalition for Change has eight, despite its presidential candidate having placed fourth with only 3.5% of the vote. Obviously the Coalition for Change has a regional base, and parties with regional strength can win under FPTP despite having a low nationwide vote total. (National vote totals for assembly are not yet available.) The party of the third-place presidential candidate, who won 6.9%, is called the National Grand Coalition, but evidently it is not. On the other hand, it also is apparently not regional, having won no assembly seats (at least among those declared).

The assembly has been increased in size from the last election, when there were 112 elected seats. This remains slightly undersized for a country with a population around seven million. The Cube Root Law would imply an assembly of around 192.

As for the assembly party system, the current assembly size, S=132 (ignoring the indirectly elected chiefs), and the use of FPTP (M=1) implies an effective number of seat-winning parties, NS=(MS)1/6=2.26. On currently declared seats, we have NS=2.45 (counting each of three independents elected thus far as a “party”). That is only a very minor deviation from expectation.

The combination of FPTP for assembly and a two-round presidential election might be expected to inflate NS due to the expected (and observed) proliferation of presidential candidates seeking votes in the first round. At least it would be so expected if one believes in coattail effects. There were sixteen presidential candidates contesting the first round, and seventeen parties with assembly candidates in at least some districts.

While the effect of the first-round threshold of 55% is not clear, we might expect it to enhance fragmenting effects, relative to a standard majority runoff. Candidates who are unlikely to win might enter anyway, hoping to deny even a strong leading candidate an outright win. Given that an outright win is more difficult in Sierra Leone than in other two-round systems, the effect might be to enhance first-round fragmentation. Under a “coattails” expectation, that fragmentation would carry over into the assembly elections, even with the use of FPTP for those elections, held concurrent with the first round of the presidential contest.

In Votes from Seats, Taagepera and I express some skepticism about coattail effects, at least in terms of their impact on the effective number of parties. In fact, we go so far as to claim that one can deduce the effective number of presidential candidates (NP) from the assembly electoral system. A more direct logical expectation, developed in the book, goes from the assembly voting party system to NP; to the extent that the voting fragmentation (measured by the effective number of vote-earning parties, NV) is over-fragmented, relative to the electoral system expectation, then NP will be inflated as well.

Sierra Leone is thus a good test case for the logical models of Votes from Seats. First of all, it has changed its assembly size twice now, while retaining FPTP. Second, as noted already, it combines the FPTP assembly electoral system with a two-round presidential formula that might tend to increase fragmentation of the presidential contest. If it does so, it may also tend to increase NS and NV, if coattails explain assembly party-system fragmentation. In a table below are the results, showing all three actually observed effective numbers (NSNVNP), where available, and the expected values. The expectations are derived from the seat product (MS) in the case of NS, but for NV, we should use the derivation from observed NS, because if the latter is over expectation, for sure NV will be, too. For NP, the table reports the expectation from NV, which is the more direct route. Again, if NV, is higher than expected (perhaps because so is NS), then NP will be, as well. However, we can also compare the institutionally grounded expectation, derived from MS only.

What we see is that NV was far “too high” in the initial election under the current constitution, given the quite low assembly size. So was NP, and thus it looks like a “win” for the coattails expectation, perhaps because as an initial election before the civil war (starting 1991) was fully settled, many candidates may have entered unsure of who would be viable. The 2002 election, following the settlement of the war, also looks like a case of coattails, as the winner easily dominated the field, leading to very low values of all three effective numbers.

Nonetheless, on average, the institutionally derived expectations perform well. Even with the first election being well off the expectation (and the second, too, albeit less so and in the opposite direction), overall, the ratio of observed NS to actual has been only a little above 1.00; the ratio of expected to observed is 1.153, shown in the bottom line. (If we ignore the anomalously fragmented 1996 election, the mean NS is 2.175, or slightly below the expectation from the assembly sizes used in 2002-2018.)

Given actual NS, the observed NV has been almost exactly as expected, on average, with a ratio of 1.025. And while the slight over-fragmentation of the average assembly election result in Sierra Leone gets magnified when we look at expected NP from MS (i.e., from the assembly electoral system only, for which the ratio is 1.225), the expected NP from observed NV is not too far off, with a ratio of 1.16. Note that the ratio for NP from observed NV is almost the same as the ratio for NS from the assembly seat product.

Thus, even with a presidential electoral formula (super-majority runoff) that theoretically promotes more fragmentation than the assembly electoral system (FPTP), there is scant evidence–beyond 1996–that we are unable to predict the assembly party system from the assembly electoral system. There is also scant evidence that we can’t predict voting fragmentation for both assembly and presidency from the assembly party system. The small over-fragmentation of the assembly party system, on average, gets carried through to the other measures. This over-fragmentation might be due to the fragmenting incentives of the presidential electoral formula, but only in 1996 is the evidence for such an explanation, based on candidate entry and their coattails, compelling. Otherwise, it seems the assembly seat product allows us to get a pretty good handle on the output indices of Sierra Leone’s elections.

The seat product model, based on the assembly electoral system, performs well, even in a new post-war democracy like Sierra Leone, and even given the country’s somewhat unusual combination of institutions.

Apricot blooming, 2018

The ‘Canadian White Blenheim’ apricot has reached full bloom. It has the pinkest flowers of any of the ten or so apricot varieties I’ve ever grown over many years. Strange, given that its fruit has one of the palest flesh tones of any apricot.

Canadian White Blenheim

This variety has fruited for me before, both here and in inland San Diego County. However, we have never had more than a few fruits in any one year, and the modal number of fruits of this variety per year has been zero. That is because it has had blooms that were anything but profuse. It is a pretty clear law of fruit-growing that if you have no blooms, you get no fruit.

In past years, when this variety has bloomed, it has been not only sparse, but also very late relative to the leafing out. That is unusual, in that most stone fruits are at full bloom before leaves really begin to emerge. I always assumed that the culprit was chilling; a stone fruit is unlikely to have a proper bloom if it has not met its winter chilling need during the dormant period. (Dave Wilson Nursery suggests 700 hours chilling needed for this variety.)

There was no question of chill not being met this year. While January was quite warm, both December and February had good long periods of chilly weather and deep cold snaps. In fact, the big fear I had was that an unusually late cold snap would adversely affect fruit trees, many of which typically begin blooming here by mid-February. Indeed, the ‘Flavor Delight’ aprium was in full bloom just when a hard freeze hit. While the tree’s foliage has recovered, there is no sign of any fruit set. The freeze hit it at just the wrong time.

Meanwhile, the ‘Royal’ (‘Blenheim’) apricot has had an odd spring. Normally, it would be blooming in mid/late February. It has a relatively low chilling requirement (from much experience, I’d estimate it at around 350, even though many catalogs and other sources say 400-500). Yet it remained mostly dormant until well into March. And it was not just my own rather old tree; a few trees with ‘Royal’ tags on them, planted on the UC Davis campus a few years ago, did the same. This is very strange.

Perhaps even stranger is that just now my ‘Royal’ is blooming like the ‘Canadian White Blenheim’ normally does–after it has leafed out. It has about a dozen blooms right now, scattered amidst well developed foliage.

Royal apricot

In many years of growing this variety, I have never seen it do this. So, just as one variety that normally blooms sporadically post-leaf-out is instead having a more normal-looking bloom, here an old reliable is exhibiting the staggered behavior of a tree that got insufficient chill.

It has been an odd winter, and even odder bloom season. It is too early to know if the white apricots will set fruit. I express that in the plural, because the ‘Monique’–another even whiter variety that also is hard to get to set in our climate–also had a pretty good bloom this year. The ‘Hunza‘ (a real favorite of mine with luscious complex-tasting flesh and an edible kernel) also is in full bloom right now.

So, while one can’t count one’s fruit this early*, indications are promising for the later-blooming trees. Another law of fruit-growing is that a profuse bloom does not guarantee a good fruit crop, but it certainly makes it more likely.
*Today is the eve of Pesach (Passover). Somewhere in the Talmud it is suggested that Shavuot is the “Yom Kippur of fruit trees”, the day one which they are judged. That is about right, as in roughly fifty days we will have passed through (over?) the most perilous time for developing fruit. What holds that long has a pretty good chance of making it.

Oats, 2018

It is interesting to compare the neighbor’s oat farm today, on the eve of Pesach (Passover) to what it looked like five years ago in a photo I posted as part of my “Oats and Passover” discussion. (The linked blog entry was posted in 2015, but the photo was from 2013.)

Unfortunately, the fence has fallen over since I took the 2013 photo, making it hard to judge the height of the oats at the edge of the field. Even so, it is pretty obvious that the crop has grown far less this year than in 2013 at the same point.

This season, we have had only about nine inches of rainfall at this location, and more than 40 percent of that has fallen in March (hence too late to have contributed much to the oat growth, at least thus far). By contrast, 2012-13 was a wetter year. At nearby Davis, according to Golden Gate Weather, 13.47 had fallen by the end of March. Perhaps more importantly, nearly eleven inches of that had fallen in November-December. (We had just moved in days before the photo was taken in 2013, so I don’t have records for this location.)

Oats, at least here, are not irrigated. The crop depends on rainfall. In the time we have been here, it has been rather up and down. And each year around this time, a glance at the oat farm would provide a good clue to the rainfall patterns.

The oats are typically harvested in April. In some years very early in the month, but this year the harvest probably will be much later.


I guess, given the topic of oats and the link to the earlier post on the topic, this counts as my pre-Pesach post. So chag sameach to all celebrating!


President of South Korea announces constitutional reform proposal

South Korean President Moon Jae-in has announced his support for amending the South Korean Constitution to allow presidents to serve two four-year terms, instead of the current non-renewable five-year term. Moon, of course, came to office following the impeachment of Park Geun-hye, who became embroiled in a corruption scandal at the end of her non-renewable term: a similar fate befell her predecessor, Lee Myung-bak, who was recently arrested for a wide range of corruption charges.

Presumably, the idea behind this proposal is that it will encourage presidents to improve their behaviour at the end of their terms, given that they will be entitled to seek re-election. The proposal would also mean that members of the National Assembly would serve terms of the same lengths as the President, although elections to the two offices would not become concurrent–indeed, given that Moon’s term expires in 2022, and that the National Assembly’s term expires in 2020, it would shift South Korea to having legislative elections consistently in the middle of presidential terms.

The proposal has a number of other features. The Prime Minister will no longer be expected to act “under order of the President”, the voting age will be lowered from 19 to 18, and the President is no longer able to appoint the head of the Constitutional Court. However, there would appear to be no change in how the Prime Minister is appointed or removed: the Assembly can only pass a motion recommending that the PM or a minister may be removed, which both Samuels and Shugart (2010) and Robert Elgie have interpreted as not being sufficient for semi-presidentialism. The Prime Minister will also remain nominated only by the President (subject to Assembly confirmation).

Passage of the amendments requires approval of two-thirds of the National Assembly and majority support at a referendum with a majority turnout threshold. Moon’s Democratic Party only holds 121 seats in the 300-member assembly, and the opposition right-wing Liberty Korea Party holds 116, giving that party veto power over any potential amendment. That party appears to oppose the amendment proposal, instead apparently supporting a switch to semi-presidentialism, although the Democratic Party could block that. Moon’s proposal has greater public support, although the vast majority of the electorate support at least some change.

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.

*Thanks, Dan W.!
