I would say there is near zero probability that Obama would be declared ineligible on this basis, even if it is possible. The necessary documents to prove BNA status one way or the other are not public and may not exist. A means of bringing this speculative dual citizen matter to federal court hasn't been achieved, so far. The federal court simply cannot entertain speculation. Even if Apuzzo and Donofrio want Obama’s 1948 BNA admission to be taken as fact on Obama’s word, no-nonsense federal judges appear unlikely to touch such speculation, even if “against interest”.
It seems to me that the Indonesian events have nothing to do with Obama’s NBC status as all Indonesian events occurred subsequent to Obama's birth. Even if Indonesia doesn't recognize dual citizenship (set aside NBC status for the moment) Indonesia's law does not govern US citizenship. If it can be proved that Obama renounced US citizenship to obtain an Indonesian passport to get foreign student benefits for example, that would matter but without proof, that is just speculation that a court can't touch it. I keep coming back to a verified non-US BC knowingly hidden by Obama as the only thing Obama has to fear. A HI BC based on a home birth would leave open such a foreign birth possibility and that is the only reason I can come up with for Obama to hide his HI vital record.
File a suit that says, very simply, "the defendant has publicly stated that a foreign government "governed" him at birth", "your honor, can a US NBC be governed at birth by a foreign power?"
Would the court simply "take his word" that such was the case? Or...would the court order discovery? If it turned out during the discovery that his (alleged) father's marriage to his (alleged) mother was not legal...and therefore he didn't have British citizenship at birth and therefore his public statement admitting such is not truthful...at least discovery would have occurred, possibly answering MANY other questions about Barry (i.e. real place of birth, real father, real mother, real birth date, etc).
Why not challenge him on his own "admission" of being governed at birth by a foreign power?
