It’s not surprising the Left hates Mormons. Mormons are more likely to be social conservatives than the average population, and more likely to be fiscal conservatives.
It’s even bigger than that; the left’s whole tactic has been divide and conquer from the start. However, at least here on the right, we unite around someone who proves how capable he is. I wasn’t always a Romney fan, and could care less about ever joining his religion, but in the mean time, the guy shows more class, and more maturity than Obama ever has, not to mention, he actually shows some points to people whereas Obama is obssessed with trying to go after him. I honestly feel that even if leftists pulled this off, it wouldn’t do much to change the election, anyways.
