One fact nearly all Republican primary voters know is that former Massachusetts Governor Mitt Romney is a Mormon. 83% of GOP voters in the latest Economist/YouGov Poll (Week of 2/11/2012) say he is. By contrast, less than half of Republican voters know that Newt Gingrich and Rick Santorum are Catholics.
The issue for Romney is that nearly half of GOP voters say it is important that a "true conservative" (something many Republicans say they are looking for in a nominee) be a "true Christian guided by Christian beliefs and morals." And for at least some Republican voters, Mormons don’t qualify. Last week, less than half of GOP voters (46%) said they think of Mormons as Christians. 72% of GOP voters think Catholics are.
