I saw something similar at the Birther Report website. Regardless, the issue has never been litigated and needs to be. We should not at this point be arguing about the meaning of natural born citizen as it applies to the Presidency. Our experience with Obama should have been the call to act. Instead, we have the GOP saying that now that our guys are involved, Cruz, Rubio, and Jindal, there is no problem where you are born, whether you are a dual national or not, or whether both of your parents were citizens or not.
Unlike the Reps, the Dems will make it an issue if either Cruz or Rubio gets the nomination.
