Missed it in one. The U.S. Constitution prohibits the law from requiring an office holder to belong to a specific religion. That is precisely what is not being discussed here. What's being discussed is that the voters will exercise their God-given right to choose their own leaders on any basis they choose.
Romney is well aware that an unconstitutional religious test is being applied to him,
I doubt that he spoke to His Excellency Gov. Romney on the topic directly, as I'm sure Romney is far more knowledgable about the Constitution and realizes that it has nothing to do with what criteria the voters use to pick their President.
Unconstitutional for voters to include religion in their analysis of a candidate?
Are we sure this is from Novak ... and not from some junior high school newspaper?
