Well it looks like after four years of Trump and the GOP's efforts at amping up the spreading of racist hate, fear and suspicion, the party's rank and file have manifested themselves into a state of paranoia which is exactly what their leadership was going for.
I mean, if you can't win elections based on policies that directly benefit the working class and the poor of which the Repub party's aristocrat class' find themselves in, then scaring your constituencies into ignoring their own self-interests and replacing it with the highest priority being the survival of the GOP leadership and their wealthy benefactors is their only way to go.
And what a hell of a job they've done doing just that.
