Trump is unique. The fact that he is so hated amongst his non-supporters makes it tough to compare him to anyone else. I can't remember who said it recently in the media, but his ceiling and floor are both in a tight range. He has a base of support that will never waiver. And he has the vitriol from haters never seen before. Somewhere in the middle are folks who do not like Biden / Harris policies but have to really hold their nose to put Trump in. From that standpoint the only way he might ever grab the popular vote was if he was running against a senile old man.But the fact that you have to do it shows you're in a bad state.
It's like I've said on here before, if we're talking about the GOAT or just behind Reagan, this thing ought to be over. No sweat. If Harris is an idiot, she wouldn't have a chance vs. a Ronald Reagan. So either she's like a real heavyweight or the Republicans have let a very weak candidate run their party for 8 years now. Even after he lost.
Regardless - make no mistake, idiot or not (I think she is), the only reason she has a chance is that she's running against Trump. I think that may be your point.
