Trump. Not only is Biden going to lose, he's trying to lose.
Why would he want Trump to win?
He's flip-flopping on Israel/Gaza instead of taking a position and sticking to it. It might be a lose-lose situation, but he's managing to infuriate both sides. As to why he wants Trump to win, I'm not entirely sure - that's the main hole. Maybe he doesn't want to deliver what his base wants. But if he didn't want to be President anymore, he shouldn't have run for reelection.
