If so its because the cancer is spreading out from DC. If you know the people that live there you’d say no way in hell (I have family there). Now their politics probably or the reasons stated...
I fully believe it is because of very tight geographical imbalance of the demographic - DC disease. I think the rest of Virginia is as it has always been. They have just been infested and outnumbered now.
Take a look at NY state...there are probably three small (geographically) districts/cities that are rabid Democrat liberal. The rest of the state is what I’d consider normal American. Problem is the voting population size in those three areas.
