I’m very suspicious of DeSantis. I would still vote for him if he got the Republican nomination, but I’m supporting Trump for the GOP primary.
It’s not just about who is more likely to win. Republicans choose McCain and Romney because they could win, and not only were those assholes enemies of the GOP base and their interests, they even lost their elections to an extreme leftist.
At least for now, Trump is the head of a movement to fight not only against the left, but against a bipartisan establishment that is completely corrupt and evil. If DeSantis runs against Trump he effectively becomes an enemy of that movement and a tool of the establishment.
