Huckabee is egomaniacal and wishes for us to have a theocracy. Not only that, he is slimy. Years after he was married and after he gained influence and power in Arkansas he and his wife moved into a new big house and did the Marriage Registry thing to get his freinds and all those he has given favors to send he and his wife free gifts to stock their new home.
He also has lots of enemies in AK who has split from him. Hillary would love to run against him, since she too knows all the AK dirt. It'd be a race in my opinion of scum versus scum.
