Accepting pleas from other comments here, Canada could get away with about this. And if they have the whole Pacific border, I'll also throw in Hawaii for free.
You'd have to create a corridor through Southern Idaho and Northern Utah to join the new state of "New Mexirado" with the rest if you removed Arizona... Hard work, but I believe it could be done.
Theres citylife washington and middle of nowhere washington. Occasionally middle of nowhere washington likes to throw fits in the city to support trump because they have nothing better to do
Though i guess that goes with cali as well. Lots of the non cities in the west coast just really love trump despite reaping all the state benefits that are very non-republican.
You don't wan the middle of PA... Maybe if they just turn everything between Philadelphia and Pittsburgh into a weapons testing site? Turn it into "no man's land" like it was always mean to be.
