In the Kennedy case, the nation was not aware that Kennedy was anytrhing but a devout Christian Catholic (remember Frick and Frack?), so there was a fear that a devout Catholic would be under advice from Rome. Of course Kennedy was not a devout Catholic so that was a baseless fear. With Milt Romney, perhaps the same is true, he certainly doesn’t live up to the supposed standards most LDS claim to adhere to does he! But then again, LDS inc is a corporation, so as a devout buisness man perhaps Milt will be taking advice from Salt Lake? With Milt one never knows. Basing things on the Mormonism apologist who work FR to spin the heresies at the heart of Mormonism, I don’t think I want to trust a Mormon in the White House, devout or otherwise.
Nixon was a Quaker man I thought those folks were pretty devout too until I heard about Tricky Dickey.
