I've often wondered how many people voted for Obama just to prove to the world that they are not racist. Or in other words to show their moral superiority. I think the same dynamic was in play with Hillary - all she talked about is how "we'll make history" meaning "let's show them how forward thinking the nation has become that we can elect a woman president". IMHO backlash against that crap is exactly why Trump won, and I've had several people confirm that.
