What law are you using?
I should think that after 8 years of an Obama presidency, someone who believes that both parents must be citizens at the time of the candidate's birth has some explaining to do and they can begin with the question of why the Chief Justice of the Supreme Court (from an opposing party) volunteered to administer the oath to someone who (under these Swiss theories) would be clearly ineligible to serve. And, why did so many of the other justices volunteer not once but twice to attend the celebration of that president's inauguration? If these Swiss theories are so obviously correct, why don't the justices of our Supreme Court see that supposed truth?
