That might influence it a percent or two.
They claim 6 million members in the U.S. I bet it’s more like 2 million including all the many splits they’ve had, like the fundamentalists and the strangites, etc.
So 2 million mormons out of (142 million voters (2004) * 39% republican) = 55 million. Okay maybe 4%. Still don’t believe the poll.
It would be easy to skew the poll though. Just oversample utah.
OK, but on the other side of the coin, I imagine because Democrats are more anti-religious, they would be more inclined to be skeptical of Mormons. I think it’s at least a common stereotype that Mormons are against drinking alcohol, so more liberals would be against them because they perceive them to be that uptight, religious type they generally dislike. More Republicans might accept them because they believe they have conservative political beliefs and that’s more important to them than their religion.
