I think you are focussing a bit too much on Trump here...
If he goes away, who follows him up? J.D. Vance? ... because without new elections, you are pretty much stuck with the G.O.P., who at the moment are loyal to all those backers of the Herritage Foundation and the entire Conservative news circus that bombards people with falsehoods. You'll still have a 35% indoctrinated electorate to deal with, that will just rationalise everything away by blaming some out-group they don't like.
Focusing on Trump, seems useless to me at this point. There is just a bunch of people begging to be safed by some authoritarian guy that blames everything (even their own mistakes) on people they don't like.
... next to all that... I still don't see any of this passing the senate. Because those 35% are the ones that have guns to save themselves from tyranie... by installing their own tyrant. And republicans have already expressed, how they are being threatened by the most vocal and violent segment of their voters.
