Romney: Mormon on A White Horse?

Strictly in the interest of general study of indigenous American religions, I'm sure, a Giuliani campaign staffer alerts bloggers to a Salt Lake Tribune story on a bit of Mormon lore (not believed by all, or even most, members of the Church) regarding a supposed Joseph Smith prophecy regarding a Latter Day Saint who will ride in on a white horse to save the U.S. Constitution. Ryan Sager at the NY Sun has the details.

Update: Rudy's camp apologizes.
