The ideological leanings of Mormons have become of greater interest in recent years as a result of Mormon positions on the moral issue of gay marriage. Mormon efforts on behalf of the successful November 2008 Proposition 8 in California -- which restricted legal marriage to opposite-sex couples -- were in particular subject to intense media focus.
Although it is assumed that Mormons are conservative, their relatively small numbers in the U.S. -- about 1.7% of the 18+ adult population in Gallup's tracking -- make routine survey analysis of their political and ideological leanings difficult. Gallup's large database of Daily tracking interviews allows for the aggregation of enough Americans who identify as Mormons to conduct meaningful analysis. The current analysis of Mormon ideology is based on more than 350,000 Gallup Daily tracking interviews conducted in 2009, including 5,819 interviews with Mormons.
