This isn't genuine. Huckabee knows what he's doing. This makes him 50x worse than Santorum, because at least Santorum is genuine about his awfulness.
I agree. He said the other day on the Daily Show that he is "planning to" run for President. This matches his book about the "good ol' folk" and his basic populist rhetoric. None of this was coming from him when he ran in 2008. He knows what he is doing and what voter group he is trying to attract, and it is incredibly annoying (just like the voter group he is trying to attract).
