Mormons lean more heavily toward the Republican Party than any other major demographic group, whether clustered by race, age, gender, educational attainment or religion.
So says a study released Tuesday by the Pew Research Center, based on more than 25,000 survey interviews conducted nationwide in 2014.
The survey shows that 70 percent of Mormons lean Republican, compared with 22 percent who tilt Democratic. That gap is greater for the GOP than margins provided by any other group.
Behind Mormons in GOP support are white evangelical Protestants, who give the party a 46 point edge; white Southerners, a 21 point GOP advantage; white men with some college education or less, also 21 points; whites, 9 points; and the “silent generation,” ages 69 to 86, 4 points.
Groups that lean Democratic most heavily are blacks, who give that party a 69 point edge; Asians, a 42 point margin; religiously unaffiliated, 36 points; post-graduate women, 35 points; Jews, 30 percent; Hispanics, 30 points; and the millennial generation, ages 18 to 33, 16 points.
Jocelyn Kiley, associate director of the Pew Research Center, noted that Pew did a large survey of Mormons in America in 2012 and found then that about three-quarters of Latter-day Saints in the West are Republican, compared with about two-thirds of them in other areas.
“Mormons are a strong Republican group, no matter what subgroup of Mormons you look at,” she said.
No other religious group identifies so strongly with one party, although some come close.
About two-thirds of evangelical protestants (68 percent) lean Republican, and among Jews, 61 percent lean Democratic. Catholics lean Republican by a 50 percent to 41 percent margin, while mainline Protestants tip Republican by 48 percent to 40 percent.
“Mormons have been heavily Republican for quite some time,” said Quin Monson, a political science professor at LDS Church-owned Brigham Young University. “What is surprising is they have been getting more Republican in recent years in terms of their voting behavior,” especially because of Mitt Romney’s 2012 White House run. (Romney became the first Mormon to win a major-party presidential nomination.)
Monson co-wrote a 2014 book, “Seeking the Promised Land — Mormons and American Politics,” which examines why members of the Church of Jesus Christ of Latter-day Saints are so heavily Republican.
