Remember the original map published in USA Today was of red and blue counties that had voted for Bush or Gore. There was an important point in that map, which was that the Blues are pretty much only in the big cities.
So, I agree Red States (states that are almost all Red, and states that have GOP majorities in their government) will break in our direction. And some very blue states may break that way. But a lot of the rest of the states are really Red with big Blue urban cores in them. It's not clear how this works itself out.
Maybe the urban cores are big enough to direct the state over the will of the "red counties". Or, maybe not. If you read speculative fiction there is a lot of it that deals with the cleansing of the polluted urban cores in states like Washington and Oregon.
Even in New York you see a clear divide between the gun-grabbing libs and their patrons in metro New York and the upstate region, with it's indigineous population which is highly pro-gun.
