I don't regret voting for the man in '16 and '20, but he doesn't deserve my vote in '24. If he's the nominee, there is absolutely no way he can or will win. His negatives are far too high to overcome, and that would be assuming he'd want to overcome them. Which he won't because Trump doesn't learn anything. There's too many people who won't vote for him, and there's no way anyone can change that. He won in '16 because Hillary was the same kind of toxic candidate Trump is now.
Make him the nominee if you want to guarantee a 2nd term for Biden.
