I feel like Trump is too unique to be treated as part of a conventional Republican/Democrat divide.
The 2016 election basically IMO was just about rejecting the post-WW2 consensus world (I think the biggest part of Trump is that he's 70 years old)
In that world, people tried to be nice to each other and get along even if they had different values, whereas the 2016 world was increasingly about extreme identity politics and kind of pockets of culture that rejected each other.
For instance, a lot of states in the US in the 2000-2016 period, in response to the perceived failures of internationalism because of issues elsewhere, or perhaps actual failures, undwerwent revolutionary changes in outlook and began to shed what they perceived as the burdens of the past.
States like Texas, Georgia, Florida, Ohio, Missouri, Wisconsin, Iowa, Wyoming, Montana, Lousiana, mainly southern states but a good share of northern states as well began to perceive the consesnus world as treating them unfairly, and therefore were going to go their own way.
I think to an extent this is a global trend but I'm not really sure, to be honest.
This manifest itself with nativist politics and also things like the neo-Confederacy movements etc, but also imo equally a kind of "work hard old steel town" perspective in places like western Pennsylvania, Ohio, Michigan, Indiana (lest we forget who Trumps running mate was).
This was likely to bloom into full blown neo-Nazism and such, but I think Trump as the member of the consensus world stole the thunder out of all the movements, including the alt-right etc.
It's ironic of course because that would mean that all these states voted for their own worst enemy, I would expect Trump and co. to in the near future begin dismantling all the nativist politics of all these states and so on, and basically become their worst enemy, because he's a New Yorker really not so much of a red state guy as just the most maligned member of the post WW2-Consensus world.
So basically I think of the 2016 election as the US wanting to get rid of the Boomers and all their world regardless of exact political affiliation, and that world instead seizing the election and retaliating and destroying all the radical statist movements in the US.
Basically Trump is a democrat from New York and who is closely associated with and identifies strongly with a lot of the Blue States, particularly on the east coast and New England, who the democrats and blue states wanted to completely destroy the Republican party and all the Southern culture and midwest culture etc in the entirety.
And which is more or less happening, in slow motion, but, nonetheless.
So now the only divisions are basically between kind of western blue democrats who are more Clintonian and east coast/New England Trump democrats, with the Republicans and middle states ceasing to be in US politics.
