So here’s an easy way to game this type of poll:
Take the survey among only target voting populations in the west, where there are more Mormons.
Among east-coast Catholics I’ve known (eg, Italians in upstate NY), their support or tolerance of Mormons is nowhere near this - and isn’t above 50%, either. Matter of fact, their tolerance of anyone who isn’t Italian and Catholic was one of the reasons why I left the area 30 years ago.
Well, this is only anecdotal evidence, but... Most of the Italian Catholics whom I know voted for Romney. But I don’t live in NY, and this small sample wouldn’t represent the entire population. There’s no doubt there are other Catholics voting Democrat.
