I mean Trump is pretty old so even if he’s somehow a dictator (he’s not, he’s just a demagogue that’s very disagreeable - 2 traits that often lead to success if used well) he won’t around that long, lol.
I believe it’s the opposite. His personality cult makes him singular, irreplaceable. When he’s gone, it’s over. The movement will just be left with its policies, which were an afterthought for most voters and might not even give favourable results.
As I interpret this thread people aren’t so much worried about Trump as they are about the Republican leadership. Particularly the American justice system will get packed with powerful conservative judges. The US is likely going to have a Supreme Court which will be far more conservative than the average citizen for the lifetime of most of us.
Similarly the FCC chair wouldn’t magically become “better” just because it wasn’t Trump. As crazy as Trump is in my opinion, he still comes off as rather progressive compared to much of the Republican Party he is the president for. A party which will again make the most out of Trumps wild ride, like they did last time.
These things will far outlast Trump and his followers. Followers who are probably also much more progressive than large parts of the Republican Party they elected.
