I have a hard time believing the average Mississippi/Alabama Republican is more liberal than the average California Republican. I mean, 65% of Mississippians said in a 2000 poll (I think?) that AIDS was a punishment from God, so that would've meant 80%+ of GOPers.
Why do you have a hard time believing that. In Mississippi and Alabama you'll get moderates who don't care too much about the parties participating in politics as a Republican because of the bandwagon/wasted vote syndrome. In California, you have to be a true believe to bother with being a Republican.
