What are you confused about exactly? Fascism always start on the fringe and it works its way into society because the "moderates" become complacent, fat, and greedy. In the US bribery is legal, and Democrats have become more concerned with protecting their corporate bribe scheme than protecting our democracy and stamping down fascism.

That's how it works every time -- corruption renders institutions unable to combat fascism, which is why when the take over actually happens it doesn't take a ton of force to push things over, they just push the door open and walk in.
