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.
