If you vote for Mike Huckabee for President, either in the primary or the general election in November, because he was a Christian preacher, you're as big a fool as someone who votes for Barack Obama because he's black, or Hillary Clinton because she's a woman.
Of all the reasons I can think of to vote for someone, their race, sex or job they held in the past (that has nothing to do with the position in contention) is nothing but a non sequitur. It's like saying, "I'm a Miami Dolphins fan because they've got a cute uniform," except with serious and meaningful consequences.
