Words are inadequate

No, we pretty much agree. You're correct that batshit branch of the Democrat party is rather marginalized within it - and doesn't have a substantial voice much to their considerable annoyance(or Bernie Saunders or the crazy lady two steps left of him would have gotten the nomination not Biden or Hillary (in 2016) ). While, yes, the batshit right has pretty much taken over the Republican Party and become mainstream.

What happens next will have a lot to do with whether they manage to get the New Voting Rights Act Passed, and kill the filibuster or at the very least scale it back to its former incarnation in the Senate. I think it will be scaled back, and possibly done away with - in order to pass the Voting Rights Act. The Voting Rights Act - will kick some of the new state level restrictive voting legislation and gerrymandering to the curb.

If they pass that Act, then yes - the Republican Party most likely will begin to disappear into irrelevancy. And lose the Senate within two years. With no candidate getting very far into the elections of 2024 and onwards. If they keep going the way they are - the Presidential Elections may well be decided within the Democratic Primaries, or with be a Democrat vs. an Independent, with the Republicans in third party status.

If they don't pass it? We're stuck with the fascist bastards.
