American elections are won and lost on turnout, and the vibes-based voters are the most likely to stay at home. All those people who said the main reason they didn't approve of Biden because of his age will vote for Kamala as long as she doesn't fuck it up. Plus there are a lot of libs that are currently convincing themselves Kamala will be better policy wise, anything she says will make things worse.
My opinion is that to win, all Kamala has to do is not be Biden. Go hide and say nothing. She's not going to do anything in a debate with Trump that's going to win votes, but she could do something to fuck it up.
I think Trump hoped January 6th to be that sort of event, but it failed miserably. It failed because the only people willing to do anything about it were the chuds that showed up to his rally. They lacked any kind of shared political theory or goals. Some were there to have fun, some were there because they believed in Qanon, some wanted a christofacist dictatorship, and some thought they could fix the "voting irregularities" and go back to being a representative democracy. All those same impediments exist today for any kind of dismantling driven by citizens.
It could still happen if Trump suddenly got institutional backing for such a thing, like from the military, courts and big business, but it seems super unlikely. The bourgeoisie gets everything they need from both parties, why send America into economic chaos to keep one dipshit in charge?
