I think Trump himself will fade from view rather quickly.  Apparently Rupert Murdoch thinks so too.

For  my money, the immediate danger for the left lies in the right-wing coition between Biden and the "good republicans" with whom he is allying himself in order to purge the US once and for all of any possible taint of "socialism."  The alleged "liberals" of the Democratic Party are 100% behind this. When Biden croons "heal" the left should hear "heel!"

The "good republican" Romney has already said he supports the eternal servicing of the Trump legacy as the Prime Directive of his party. What this means at least is that the Republican Party will look at Biden's proffered hand of brotherhood and bite it off.  

This always happens and the Reaganized "liberals" of the DP never see it coming.  They will be heartbroken and in need of therapy--and will blame the Left, even though by then there probably won't be a single self-identified socialist anywhere near government or even on the Internet.  All they've ever wanted out of life is Good Republicans--how can this be happening?

IMO the Republicans will take both houses of Congress in a tidal wave in the mid-terms, and 2024 will be theirs to lose.  Will that play out in another shambolic right-wing anarchy or in "fascism"? Or what? And will Romney and the rest of those assholes be able to control the monster they are so clearly planning to conjure up once Biden walks into their trap? We won't be hearing the Horst Wessel Lied but, contrary to the kneejerk reflex, there are plenty of political worst things that can happen that aren't "fascist."
