I don't think Mormonism is weirder than Freemasonry. In fact, I think they have a lot in common. Neither Freemasonry nor Mormonism reflects my own faith, but that doesn't mean their adherants can't be good presidents.
What is it specifically that people are worried about with a Mormon president? That he'll ban alcohol? Or coffee? I'm not joking. I really want to know why folks are afraid to have a Mormon in the White House.
