Presidential hopeful Mike Huckabee apologized to fellow hopeful Mitt Romney for asking the question "Don’t Mormons believe that Jesus and the devil are brothers?" Now, I don't know the tone in which Huckabee asked the question. In any case, it wasn't a smart question to pose, politically speaking. And for the record, I think Huckabee would be a horrible President.
But what I found most interesting is that everyone is acting like his question is extremely illegitimate. I don't think the question is a worthy question for the context of the Presidential race, but it's certainly a legitimate question for Mormon theology. Though I highly doubt many Mormon's are aware of the foundational teachings of their Church, such doctrines are still a reality.
Here's the facts. In Mormon theology, Satan wanted to be the one to save mankind. "Behold, here am I, send me, I will be thy son, and I will redeem all mankind" (Pearl of Great Price, Book of Moses 4:1). But God selected Jesus for that task instead, and so Satan rebelled against God. Brigham Young commentates on this passage: "The appointment of Jesus to be Saviour of the world was contested by one of the other sons of God. He was called Lucifer" (Brigham Young Journal of Discourses 13:282).
