I watched Mike Huckabee's phone call with God stunt (see below) very closely, but I don't think he crossed the line. (If he hadn't said that God didn't take sides in the election, it would have been clearly inappropriate. As it was, I think it was just a bad joke.)
But LRC linked to a statement in which Huckabee said Jesus must endorse capital punishment because He didn't argue against it while on the cross. By the same logic, Jesus must not only agree with capital punishment for murderers, but also for religious heretics.
The fact that Huckabee is so flippant about our (meaning his and mine--I'm not trying to convert all Crash Landing readers) Lord while He was bleeding to death... I have to agree with Lew Rockwell that "this guy gives me the creeps."
