Only 14% of Americans know that Mormons do not practice polygamy, while 46% say they probably or definitely do.
The survey from Lawrence Research finds that 86% of Americans do not know the correct answer to the question whether Mormons practice polygamy. According to the survey, that ignorance could affect voting behavior.
Of those who correctly know that Mormons do not practice polygamy, 39% would definitely consider voting for one, compared to only 26% among the rest of the voters.
Similarly, 83% of voters who know that Mormons do not practice polygamy would vote for a well-qualified nominee of their party who happens to be a Mormon (the Gallup wording), whereas only 68% of those who believe Mormons practice polygamy, or are not sure, would vote for a Mormon nominee.
