Not so much, it would more be along the lines of a standard military coup, which doesn’t necessarily have to originate from a fascist. Those can and do come from all sides of the political spectrum.
I don’t think biden would ever do that, and probably if he did, he’d be the worst president dictator of all time with only the mild upside that he could maybe only do so for the rest of his probably not long lifespan, or for the next couple months as they run another election, which he would probably do since he seems like kind of a sap.
But, if he were replaced by a person I actually liked, or there was someone who’s policy I agreed with in that position, I’d pretty much be fine with it, and I get the feeling that most people would be fine with it too, as in, a majority of the population. The levers of power might freak out though, and that might put a damper on things.
