I think it's two things:
Firstly, identity politics is a hell of a drug and Trump has put the blame for the current miserable situation on the "Wokes".
Secondly, America is a country where you have beaten into you from a young age that voting every 2 years is how political action is done. Protest are constantly put down as childish inconvenience at best and actively criminal at worst. With that in mind how as an American do you voice your frustration with the incumbent? You vote for the challenger.
