Whichever way you cut it, Mormons are not Christians.
But then again, neither is Obama and the country has reached a point that to have a Christian in the WH is of no importance any more.
I am not sure, but nowhere does it state in the Constitution that the POTUS must belong to a Christian denomination.
With the way we promote diversity and multiculturalism, it is highly likely that we will have a Buddhist in the WH in the not too distant future. And even a convinced atheist cannot be contitutionally barred from that position. (I don’t think.)
You are right; but this thread is about MORMONism, NOT American politics.
If you want to bring MITT into it though; I'll be glad to oblige.
