No doubt no Mormons but General Authorities subscribe to that doctrine ~
BTW, the issue isn't whether or not Romany worships Satan ~ that's a trivial item when it comes to politicians ~ after all, where would Satan be without his armies of politicians?!
The real issue here isn't the detail, but the "religious question" per se. All of the Republicans passed the test ~ they attend religious services with some regularity.
Beyond that, it's just quibeling.
