Peru has its presidential and congressional elections today. For presidency, it is the first round of a two-round majority election. And it is likely that the top two will combine for a very small percentage of the vote in this first round. (See polling summary.) That’s really no way to select a top leader, but that’s what you get when you have a democracy without political parties in any meaningful sense of the term. See Steven Taylor’s post today for more about that.
The combination of weak parties and fragmentation with an electoral system that uses a wide variation in district magnitude and D’Hondt divisors, can also result in wide discrepancies between national votes and congressional seats. For instance, in 2016, it helped produce divided government when the party that won a manufactured majority in congress, concurrent with the first round, lost the runoff. In the just-linked earlier post, I said that “governing may be a challenge” in the period ahead. Oh, did that prove to be a good call! (Details in Steven’s post.)
