Do you know that Mormons consider the U.S. Constitution to be a holy document? In fact, they consider it their moral duty to restore this heavenly inspired document to it's former glory. Joseph Smith stated in 1940,“Even this nation will be on the very verge of crumbling to pieces and tumbling to the ground, and when the Constitution is upon the brink of ruin, this people will be the staff upon which the nation shall lean, and they shall bear the Constitution away from the very verge of destruction.” So you think that a LDS high priest like Mitt Romney isn't aware of his chief luminary's philosophy as well as integral Church doctrine?
Secondly, your point about Huntsman is correct. He and Reid have both strayed. But generally Mormons are fiercely independent people who will go out of their way to help their neighbor. They even got along with the Native Americans.
