I remember reading that the supposed election tampering of Russia was mostly just pot stirring, basically just elevating contradictory and emflamatory narratives on both sides using trolls and bots.
I'd say about 80% of Republicans will enthusiastically support anything the GOP does
That's the maximum size of the population that could be considered violent fascists, so even if they all are invested enough to actually do something violent (they won't be), that's still "just" 20% of the voting-eligible population.
The real strength of fascists comes if they can capture the state and use its legitimacy to get their more passive supporters (and libs) to go along with state violence, or at least not violently oppose it.
The U.S. has long applied this towards the outside world (imperialism), but the frontier is getting closer and closer to home.
I read that most of the election interference was actually done by Israeli agents lol. There was a piece about it last year or the year before and it detailed Trump’s advisors having secret meetings with Israelis and coming out with new dirt on Hillary.
