Just in case you thought Christian fringe nutjob Mike Huckabee has any redeeming qualities, here he is in an interview with beliefnet....

Is it your goal to bring the Constitution into strict conformity with the Bible? Some people would consider that a kind of dangerous undertaking, particularly given the variety of biblical interpretations.
Well, I don?t think that?s a radical view to say we?re going to affirm marriage. I think the radical view is to say that we?re going to change the definition of marriage so that it can mean two men, two women, a man and three women, a man and a child, a man and animal. Again, once we change the definition, the door is open to change it again. I think the radical position is to make a change in what?s been historic.

That's pretty straightforward ... changing the definition of marriage to include two men or two women is tantamount to a man and animal.  There's none of that gay marriage opens the door to man on dog marriage logic that Santorum espoused.  Nope, Huckabee makes a much more straightforward equivalent. 

Sigh.  Not that it really makes any difference.
