Here's a rule of thumb for the nation: If a candidate announces in advance his intention to violate the Constitution, don't elect him.
So sorry, Mitt Romney, you're out.
"Our greatness would not long endure without judges who respect the foundation of faith upon which our constitution rests." - Mitt Romney
"[N]o religious Test shall ever be required as a Qualification to any Office or public Trust under the United States." - Article 6, Clause 3 US Constitution

P.S. Romney is also a liar. He's now got commercials running where he promises hard-working Americans he'll end the "Death Tax." I'm sure the 2% of the population who are effected by a tax on the transfer of their multi-million dollar estates will be thrilled to hear that their great-grandchildren will be born wealthy and never have to work a day in their life.
