I don’t buy that all these racists that wouldn’t have voted otherwise came out of the woodwork to support Trump.
Neither do I, but I think you underestimate the number of racists if not outright white supremacists that vote for Democrats, and even voted for Obama.
No I don’t.
EDIT: By the way, I’ve been exposed to my fair share of astoundingly stupid people. Your “close proximity” to white supremacists isn’t unique. I know a lot of passively racist idiots, and they don’t vote Democrat, and they definitely didn’t vote for Obama. White supremacists didn’t vote for Obama in any meaningful quantity. I see no reason to bother discussing that.
