The root problem of Trumpism isn't going anywhere, these people were largely "like that" before Trump and they'll be like that after Trump.

At best, we may find that the right is directionless after Trump, unable to unify behind a single face. There are other right-wing figures just as bad or worse than Trump, but many of them are ideologues who don't have the same kind of broad appeal. But this will only be a temporary setback. Even if the Democrats win, we'll just get more neoliberalism, and we'll get a situation like with Kier Stamer in the UK, where people got sick of the Tory clownshow enough to give Labour a chance, but then one of the first things Labour did was to cut Winter fuel subsidies and their popularity plummeted. Democrats likewise can always be relied on to drop the ball and alienate the working class.

There may not even be an offramp on the path towards fascism at this point but if there is it involves the left putting forward a bold vision that offers a plausible alternative to both neoliberalism and fascism. Otherwise, if the choice is between neoliberalism and fascism, then it's only a question of how long it takes for neoliberalism to decline to the point that people will gamble on fascism, which is what brought us here in the first place.

Don't treat Trump as some sort of anomaly or fluke, don't think that the US will stop being Trumpian once Trump is no longer president.
