California... we've got liberals, conservatives, red necks, communists, et cetera. Maybe Arizona as well.
I'm not sure how representative the desert Southwest is of the United States culturally.
California is significantly more liberal than the rest of the US, but due to the wide variety of landscape and people (farmers, loggers, huge fricking cities, etc.) I suppose there is a solid case.
I still say New Hampshire is the most. I'd say they are right about what the average American is in terms of lifestyle.
