Romney is a Massachusetts liberal that the majority of conservatives are never going to believe is conservative. Nor do many of us want to sellout our integrity and support a man that has flip-flopped more than Bill Clinton and John Kerry combined.
It's people like YOU that blow it by backing Romney instead of Huckabee, who FAR more conservative.
If by 'conservative' you mean 'one who makes back room deals with McCain', then yes, Huckabee is FAR more conservative.
