The reduction of the white population in America and the rise of black/brown people (not that I give a shyt about the browns, just saying the facts) will lead to a increase of anti-black sentiment, and a sudden increase of white/brown on black crime. You can see it online, it's only a matter of time before they really start showing how they feel in your face.
California will be yellow/whitewashed. Most of the black people will be subjugated or kicked out. There will be no more black mayors in the major cities in California or any other state in the West Coast.
One of the southern states, particularly GA, will have a black governor/Senators. Atlanta will be the stronghold of a successful black city with black businesses and black employment.
Detroit will be whitewashed. It's already happening. Blacks in Michigan will relocate to the South.
New York City will be everything but black. I saw a high-level of black New Yorkers/Jersians in VA and that was five years ago.
I can probably see another black president, maybe a Latino one.
