The difference this election was that white voters in the Rust Belt that voted for Obama or did not vote at all the last couple of elections, voted for Trump this time. Obama did save the auto industry and went thru hell and high water trying to convince them that he cared about them. I know quite a few white men that would never accept a female leader, much less a strong assertive woman. They have been hating Hillary for 30 years. Their wives stood by their men. Like the mother of a cop that may think the Black Lives Matter movement is a threat to their child, those Rust Belt mothers feared many things that might endanger their families, like the opiate epidemic in Appalachia that is effecting mainly rural white folks.  They feared Hillary didn't care about them because she cared about minorities. In their mind, caring when it comes to minorities in general and black folks in particular, is a zero sum game. Black folks gave Hillary well over 90% of their registered vote voters.
