All Huckabee needs is to win Texas, and a macaca or Howard Screeeeeeam moment.
Plus, win or lose (the nomination), if Huckabee wins Texas, it will send McCain a HUGE message.
The base wants a stronger CONSERVATIVE.
Huckabee is certainly a much stronger conservative than McAmnesty - on the life issue, 1st amendment, 2nd amendment, understand the Red China threats, etc.
Hard-line Communists are "conservative" in that sense.
