His base is getting down to those trolls who just want to see Liberals pissed off. They don't consider themselves as elite or highly educated and it's their "turn" to win. The reason he won those Midwestern states (and thus the Electoral College) is because those states contain a lot of long-term unemployed or under-employed who have stayed there instead of going where the new jobs are and resisted retraining.
They see themselves as anti-elite and proud of it. The real problem for them is that Trump can do nothing to make their lives better. The economic forces that made them that way are far far bigger than Trump. It's like King Canute beating the incoming tide. They will continue to spiral down economically until they move and get retraining (as Hillary suggested). Of course, Trump is not doing anything to help them but he's claiming he is. see "New Coal Jobs"
