Huckabee's problem, with me personally, is he tendacy to be pro-illegal immigration. He makes no bones about it. He says and tries to push bills through the Arkansas legislature that most Americans oppose in regards to immigration (granting in-state tution to illegals.)
And he's an anti-tobacco kook and wannabe food policeman.
Rapid escalation of the nanny state with him in charge (well, even more so than now).
