Faulty Premise. If one is "Natural Born Citizen" that status cannot be removed by adoption, or traveling on a foreign passport.
The notion that qualification as a natural born citizen requires that both parents be citizens is very much a minority opinion. Very few jurists, legal scholars, or politicians believe this to be true.
Ditto. (a) Jurists, legal scholars, and politicians are wildly different beasts. (b)No one has ever polled them.
Courts have avoided the issue like the plague. I predict the issue will resurface with a vengeance in 2012.
I believe that you are correct on this point. The issue is whether, if and when he took positive action to affirm his foreign citizenship after attaining majority, he surrendered his original citizenship status.
Whatever the courts might rule, I bet the ranch that he and his political handlers did not want this issue known to the American public before the election.
