re: What would be the reaction if the 2020 map looks like this?

Trump would have to get a majority of Hispanic votes and 20-30% of the black vote for a map like that.

There is a solid 25-30% of whites that are far left liberal and can’t be swayed. Demographics have made states like California and New York almost impossible for the GOP

When Reagan won against Mondale the country was still 90% white and fairly centrist on both sides with very little identity politics
