If Milei doesn't win outright and is forced into a runoff, I'm curious what the candidate who came in third will do as far as an endorsement (or if they don't give one at all) and who their supporters will hold their nose and vote for in the second round. Will their second vote cancel each other out or will most of them vote in a strategic way so that the "greater of two evils" loses, and how much consensus is there on which of the two advancing candidates is the greater evil?
I'm wondering if like Trump, Milei's support has a significant floor and a ceiling that isn't that much higher but will have a hard time bringing over opposition and undecideds to his side for the second round. Can he grow his already significant support to put him over the top or does he have a hard ceiling of support that can't be increased?
