Did you know the most important document in US History, (our Constitution) mandates that there shall never be any religious test to hold federal or state office?
See Article 6, paragraph 3.
The founding Fathers debated extensively over this clause, but finally came to this language to prevent America from having a state religion, and to assure that anyone, even ATHIESTS could be elected as President.
If the founding Fathers purposely chose a completely secular approach to who could be in high office, that should be the only standard for real conservatives, namely the Constitution..
Quote from Article 6:
no religious test shall ever be required as a qualification to any office or public trust under the United States
