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.
There is no alliance between rich urban whites and racial minorities, Trump still won the wealthiest income bracket by 1% in 2016, according to exit polls.
The Democratic Party has almost always been the party of the poor, and I hope to God that doesn't change.
I’m pretty sure the rich white areas of the vast majority of cities voted strongly for Clinton over Trump.
Trump’s rich support skews overwhelmingly in rural and suburban areas.
