Non-whites are trending republican. Why is this happening?

Friendly reminders that:

A: Hispanic is not a race
B: Many (most?) hispanics are white

Why wouldn't hispanics be able to assimilate?

Hispanics can assimilate... non-Hispanics into their community. It works both ways.

With blacks...

1.  "Black" increasingly includes "biracial" people whom whites may not accept as white. But they may think much the same as white people because the cultural influence of a white parent is stronger than that of a black parent. This may have a political effect.

2. Middle-class blacks used to be more heavily professionals in government service or have businesses that rely heavily upon people getting government assistance. That a black person be a grocer (usually  a conservative-leaning occupation) might not matter so much as that many of the customers are getting and using federal food aid. Likewise an African-American physician might have a clientele that relies heavily upon Medicaid. If one relies heavily upon the government as a payee, one might not be so concerned with taxes as on personal revenues.  Such is still so, but more blacks are getting ahead in businesses that don't have such an obvious connection to the government as a payor. 

This is slow, but any Republican President or other politician who baits black people can expect political difficulties, to put it tamely.
