Here are the 50 largest counties in America. There is a direct correlation to the vote and percentage of immigrants. The government types were always significant in VA. It was mass immigration and the domestic migration of people from the Northeast that changed VA blue.
The US will have the demographics of CA today in 2050. Does anyone believe CA will go red any time soon?
Because of this, the red may grow in the Midwest AND Northeast as much as VA, NV, CO, WA, etc., have gone blue.
What states specifically in the Midwest and Northeast? "May" is the operative word. And for what reason(s)? Unless the GOP adopts Trump's policies on immigration, trade, and placing American workers first, the GOP will go down the drain after Trump.
