Why does the Northeast have so many liberals?

Living in the Northeast, I have become frsutrated by the great abundance of extreme liberals and communists up here and the crappy weather we get. I have even seen some people wear Che Guevara shirts up here, which crossed the line. I am planning on moving to Virginia or North Carolina, but I am not sure if it is any better down there. I doubt there are many communists and liberals down there, at least.
