I don’t give one hairy shit about what denomination or faith a politician ascribes to; far more important to me is how that faith manifests itself in their life. We’ve had Quaker presidents, Bapist presidents, Anglican presidents, a Catholic president, and none of the above presidents. The most important founders were either Unitarians (like John Adams) or even deists (like Madison and Jefferson) who had a less-than-conventional view of Christianity; meanwhile, some of our worst presidents (like Harding and Wilson) claimed fairly red-blooded American Christian sects.
I’ll take a man of non-traditional religious beliefs - so long as those beliefs form an ethos based in humility, honor, and integrity - over a nominal Christian any day of the week.
Well, I think it matters if a person is following a false prophet whose word takes precedent over scripture. Such is the case with Adventists. That was a concern with Romney, as well.
