Yes, it is.
...not Mormonism
What? You have the utter gall to claim that if Newt or Rick Santorum announced Monday that they believed in multiple gods and were embyronic gods are their way to "godding" their own planet when they died that this wouldn't have ANY effect upon voters? [What true-belieiving Mormons believe]
Go on fantasizing that you're wearing a dark suit and are into heavy breathing...because that's also the socio-poliitical fantasy world you live in.
Let me provide some clarification Mormonism is not his primary problem at this time as many folks do not know the wacky false theology they have, however if he got the nomination it would become an issue which Obuggery or the MSM would exploit in the general. And as you state in your post those things would be disasterous.
