What post-2016 trends do you see forming?

Eventually, the weird alliance between rich urban Whites and racial minorities that is the Democratic Party will break under its own weight, and the GOP will gain substantially with rural minorities (Blacks in the South) and working-class Latinos.  The GOP can achieve this by becoming even "Trumpier" in the extent that it continues to make bogeymen out of neoliberal types.

In the long term, the current political alignment will reach its apogee when White voters in the Midwest are just as partisan as Whites in the South. 

This. It's a safe bet that the next realignment will be based on some socioeconomic problem, like automation. As for who's who, who knows. Maybe the GOP will end up being the rich liberal socialites' party instead.

The thing is, the rich guys always win.  The poor/minorities will be the ones to move because they’re always more marginally attached to politics to begin with.  Their interests are always kind of orphaned, so they’re less wed to certain parties or ideologies. 

Yekaterinburg, never forget

279 blue wall sticking into 2022 midterms, 2024 elections. Trump spoiled it, for forseeable future for all GOPers. After Dems win all levers of govt: packing Crts, abolishing soft money and Federal Holiday, ending Columbus Day, will be enacted

You have a strange wishlist.
