My understanding is that Hillary Clinton, John Edwards, and Barack Obama all believe that Jesus Christ died for the sins of mankind and then rose from the dead. This strikes me as a hell of a tall tale. But, obviously, it's not what you'd call a rare view in the United States and if we're going to start writing off politicians who believe in "fairy tales" of this sort there's going to be nobody left.
I like Huckabee, and to a certain extent I liked his answer, but I don't think this will quite fly. I understand that atheists and agnostics have a vested interest in arguing that all religious beliefs are equally absurd - that there's no difference between believing n the God of Abraham and the flying spaghetti monster, say, or between a belief in the possibility of miracles and the belief that the Genesis account is literally true; and that the only reason the Book of Mormon looks more implausible than the New Testament is because the New Testament is older, and so forth. But serious Christians should reject that view (for reasons that I think should be self-evident, though I'm sure I'll have reason to elaborate on them at a later date), and within Christendom there's a pretty big distinction between the faith-and-reason crowd and the kind of fideism that Huckabee seemed to be gesturing at last night. I don't necessarily object to a President who claims to be agnostic on evolution, and I think Huckabee's point that "I’m not planning on writing the curriculum for an eighth-grade science book ... I’m asking for the opportunity to be president of the United States" is basically correct. But all things being equal, I would prefer a President who can reconcile his belief in the truth of Christianity with what seems to me to be the only conclusion that reason allows for at the moment - namely, the common ancestry of life on Earth.
