It is a convoluted mess. When devising the argument, you have to go with the known facts and known law, find your counter argument if it doesn’t fall in line with what you want (but you can’t totally ignore the law).....and then bring in how each possible variation of detail would effect the analysis.
It is an incredible mess..before you even get to the Indonesia aspect of it.
As for the Kenyan marriage...there is a UK law about marriages before 1971 or 1972. That is another wrinkle to the whole mess since Ann was domiciled in the US.
I saw someone state on another site that being white would effect the customary marriage part of this as per Kenyan law. I don’t remember if I looked at that law or not. There is a Kenyan law website where you can read the old laws.
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.
