Things are quite different. While Trump was in office, he did multiple things that were worse than what Nixon did, and was never forced to leave office. I think our institutions were stronger back then. We didn’t have a very good democracy when Hoover was president, and it took many decades for the Voting Rights Act to get passed (which has recently been weakened by SCOTUS, and will probably be weakened much more). I think we’ll regress quite a bit. Republicans obviously want more of an autocracy/oligarchy. I think it’s a very real possibility we have Russia-style “elections” in the future, and I don’t even know how you come back from that. Assuming democracy isn’t completely destroyed, it may take many decades of fighting and changing the minds of the people who aren’t disenfranchised to get back to where we were. Hell, even civil war is on the table if Trump follows through on some of his more egregious promises (i.e. if he deems Democratic state governments as the “enemy within” and tries to use the military to depose them).
