Rudy’s a self-professed ideological clone of Clinton. Paul isn’t even actually a Republican. Huckabee... well he’s hated by the Clinton goon squad. God knows that means he can’t be a Republican. (/sarcasm)
Huckabee isn’t Ron Paul, that’s for sure...but he’s no conservative either.
A liberal Bible-thumper who supports gun rights does not equal a conservative.
