"Religious tests" per the Constitution apply ONLY to the government attempting to "fence out" given candidates.
If such tests applied to voters, then we would be FORCED to vote for minority religious candidates like Satanists to prove that there's no "religious test" for such a candidate.
How lame.
Religious tests apply only to WHO gets on the ballot; it's not meant to be a dictator forcing you HOW to vote among your choices on that ballot.
