An insane amount of people agree with the rhetoric, but an even crazier amount never get to hear the crap he pulls because their media feeds them constant vitriol and lies,
I live in a very blue city, and even here there are zero news channels that aren't right-leaning owned by one of 3 billionaires or corporations. And the public broadcasting has been discredited by the right for decades.
I just wish it were more obvious - listen to experts not billionaires and politicians.
