Add in the white bigots, the misogynist incels, the white evangelicals who believe that God delivered this flawed prophet to lead them, a sprinkling of Hispanic machismos, and the money-grubbers who’d vote for Mussolini if he promised them a tax cut (these are not mutually exclusive categories), and you’ve covered most of the Trump supporters.

I think the largest explanation is negative partisanship.

Many (most?) Republicans would never vote for a Democrat. Not because they always support the Republican candidate - they just always oppose the Democratic candidate. It's not a strong positive partisan affiliation for "their side"; instead, it's a strong partisan antipathy for "the other side."

The same is true of Democrats.

One of the most important recent characteristics of the modern political landscape is the rise of this negative political partisanship. Many (most?) Americans are voting against the party they dislike, rather than voting for a party or candidate they like.
