If you live in Texas you're a lot more likely to write off Romney and support Bush than if you live in Connecticut (I'm talking about people's feelings for Bush now, not in 2000, though).
Let's stop right here. Your premise is absolutely ridiculous. You're talking as though conservatives support candidates the same way they support sports teams - based on region or location.
I've never heard anything so silly. People support various candidates because they agree with their records and their politics. Period.
Ann Coulter supports Romney and Christie because she's a liberal Republican - just like they are. It's also why she hates Sarah Palin with a passion. She is not a conservative, although she did fool most of us for a long long time.
