Is it safe to elect a Mormon as President?

Having lived in Utah for 22 years as a non-Mormon, I would not consider voting for a devout Mormon as President. The Mormon religion strongly attempts to legislate their version of morality and religious views at a state level, with little separation of church and state consideration. Your statement about them not being permitted to think for themselves when the prophet has spoken is quite accurate. I could elaborate and state hundreds of specific incidents, but I'll refrain and just say that, yes, Romney would be a dangerous choice for President of the U.S.
