A massive landslide is possible, I just don't think it will be as much of a uniform improvement around the board as some people think. The kind of Democrat who would sweep the Rocky Mountain West and the South I imagine would have to be running a pretty dang populist message that might upset a few people in New York and Connecticut, thus actually driving down their numbers in those states as opposed to an Obamalike Democrat who could easily get over 60% there. Same thing could be said about a Republican who ends up winning New Jersey and New York.
It's a lot more likely that the winner would be an incumbent with a strong economy or other reason for their popularity other than their ideology.
Yes, point is though that I severely doubt any presidential candidate is going to get over 70% in New York. It's like a "how much more Democratic can San Francisco" get kind of scenario.
