Evidently this "issue" has captured the imagination of religious people around the US. Maybe they're not familiar with Article VI of the Constitution.

The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.

The popular view today would seem to be that this article was simply a "suggestion".

Well of course it was. With science now being reverted to magik and sorcery why not make such a commanding and unbiased document into a suggestion.
