I hope your triumphalism turns out to be accurate, but given that a majority of Republican voters still prefer Trump over any other candidate, I think it's premature to assume he won't run again. Moreover, the Republican Party is now nothing more than a neofascist organization devoted to gaining power at any cost, and this means they can swing a lot of votes their way. My money is, sadly, still on Trump returning to the White House in 2025 because it's easy to see how: Trump has more support than any other single Republican candidate, so the GoP lines up behind him just as before (when they doubted his ability to win even more than they do today). Then, faced with voting for "the other team" or their own "team" nearly every Republican voter ends up voting for Trump even though only a bare majority of Republican voters still worships him as their Great Orange God. Meanwhile, Democrat voters are split between far-lefties and dithering moderates, no one wants Biden to remain in place, and so turnout on the Democrat side is even lower than turnout on the Republican side. Add to this the extreme gerrymandering of districts, the supremely dysfunctional Electoral College, and you can see how easy it will be for Trump to win again despite every reason imaginable for him to be in jail rather than in power.
