I share your amazement, but I think there are reasons people voted for Trump despite all the stupidity and contradiction and craziness and bigotry and ridiculousness, which don’t get much attention in the information streams people in pro-Trump circles tend to get.
Some other factors:
* All the objections out there about Clinton. Our system tends to force voting against the other big gang party, since there’s no way to express more than the single vote taken as approval.
* All the “right-wing versus left-wing” ideas.
* Agreeing with some things Trump said, as cherry-picked by their information sources.
* The Trans-Pacific Partnership treaty.
* The different value systems and priorities of “conservatives” versus “liberals”.
* Various theories of the “right” that make “liberal” brains hurt, or just not be taken seriously, so we tend to not know or not think others could really be orienting their opinions around them.
* Anti-abortion fanaticism.
* Living in a community and/or Church flock where there is conservative alignment.
* Mostly ignoring political details.
My energy for this topic is wearing out, but ya there are some factors, plus not caring as much about or discounting the stuff that has you & me make him unsupportable. When I’ve heard Trump people (including women) discuss the awful aspects of Trump, they downplay it, say that’s just how men are, say he was joking, and generally don’t seem to take those things seriously and/or don’t give them all that much weight, and/or half-sort-of-side-with some aspect of some of the things he says.
