Hey steve, this is a really interesting question. My thoughts follow, and I'm really curious to know what yours are!

I think a large part (not the entirety) of why Trump voters voted the way they did, even the Evangelicals (let us be charitable and agree that not all Evangelicals are the same, not even close, but for expediency treat them as a unit here), boils down to two major themes:

1) Hillary Clinton was a garbage candidate from start to finish, and the DNC was abhorrent in its push to crown her as President at the expense of all else. Her and the DNC's messaging (often amplified by sloppy media operations[this is my way of saying Liberal Media Bias without sounding like a moron]) was often insulting to vast swaths of conservative Americans, and helped a) push moderates to the right, and b) get republicans voting in droves.

2) Many Americans hold political views, values, and beliefs that are better represented by the Republican party than the Democratic party. This is simple - they'll hold their nose about Trump and vote for him anyways because they fear worse outcomes from the Democratic option than the Republican option. There is often not a viable third option, and that is part of why D.T. is a thing.

Thoughts?
