The Church of Jesus Christ of Latter-day Saints showed its political might this fall by intervening in the California vote on Proposition 8, an initiative banning gay marriage, Mormons all over the country poured at least $20 million and countless hours of volunteer work into the successful effort. The church also showed its political limitations in the failed Republican Party candidacy of Massachusetts Gov. Mitt Romney, a practicing Mormon whose faith emerged as a major issue in the campaign. The three Rocky Mountain states with the highest percentage of Mormons -- Utah, Idaho and Wyoming -- showed the strongest regional opposition to Barack Obama and support for John McCain. Wyoming led the nation in this regard, giving only 33 percent of the vote to Obama.
