Regarding Mountain Meadows, see:
- The Mountain Meadows Massacre By Richard E. Turley Jr., Managing Director, Family and Church History Department, Ensign magazine, September 2007.
- LDS.org Newsroom Commentary from August 2003 on the book American Massacre: The Tragedy at Mountain Meadows, September 1857 by Sally Denton.
I don't see how this event has any relation to a 2008 presidential campaign, though.
