The Public Religion Research Institute has a useful primer on American attitudes towards Mormonism and the role of Mormons in public life.
What jumps off the page is that while many Americans (72 percent), especially white evangelicals (81 percent), view Mormons as holding religious views different from their own, 67 percent of all Americans and 66 percent of all white evangelicals view Mormons favorably. Pastor Jeffress has his work cut out for him.
The data also looks at how these broader attitudes relate specifically to Gov. Mitt Romney's campaign for the presidency.
Good stuff from the good people at PRRI.
