So is it settled that his father is a proven foreign nationalist and non-U.S. Citizen? The answer is irrefutibly YES. Therefore Obama in not a NATURAL BORN Citizen and cannot be President regardless of his birth certificate. Only a citizen born of parents who are both U.S. Citizens can be President of the United States. Our founding fathers in their infinite wisdom wanted to make sure the President would have single citizenship allegience to the United States passed down from his parents. Game - Set - Match!
