Lost in the hunger to create a scandalous story and infuse controversy into the campaign is the actual answer to the question Huckabee asked.  That answer is a resounding "YES!"  Here is an excerpt from a Q & A on the official Latter Day Saints (Mormon) website.

On first hearing, the doctrine that Lucifer and our Lord, Jesus Christ, are brothers may seem surprising to some - especially to those unacquainted with latter-day revelations.  But both the scriptures and the prophets affirm that Jesus Christ and Lucifer are indeed offspring of our Heavenly Father and, therefore, spirit brothers.

There you have it.  (For those who may not know, Lucifer is a biblical reference to Satan.)

What Huckabee asked is a simple question of Mormon doctrine.  It would be no different than a Muslim candidate asking, "don't Christians believe Jesus was born of a virgin?"  And it would no more an attack on someone's religion than that.

Yet, Romney chose to accuse Huckabee of that very thing.  Either Romney is ignorant of his own religion's teachings, or he is using a valid question in an opportunistic and disingenuous way to gain political points while harming a political rival.  This whole episode is just another indication of the untrustworthiness of Mr. Romney.  My unwillingness to support him has everything to do with that and very little to do with his Mormonism, strange and anti-Christian doctrines notwithstanding.
