"Huckabee has charm?"
yeaaaaa well we need a hellofalot more in a POTUS than just "charm." LMAO
and I won't even dignify your jimmy carter reference with a response.
But charm surely helps, especially if one is a Republican. Necessary if not sufficient. About Carter, the point is that he came from nowhere, a dark horse. A more recent example was Perot. Candidates can catch fire. So wait and see.
Huckabee and his wife don't have the temperment to get through a presidential run. They get a little nasty when things don't go their way.
