IMO, if Obama was born in Hawaii, he is natural born period. Case closed. If he was born outside the country, then there are some real questions since his father was not an amcit. It would also be very relevant if it were found that Obama's mother was not married to the father. In fact, it would be better for Obama if they weren't.
I do not think it is as clear cut. Another question that could come up is his father may have already been married to another woman in Kenya.
I still blieve that the Justices need to be very cautios about the Framers concerns about foreign agents and their children. It was a major concern. This is especially true with Obama when he may have held multiple citizenships and where he has sealed all of his records. He won his Senate seat by unsealing the divorce records of Senator Ryan (?) in IL. This is after Ryan and his ex-wife legally objected to unsealing the case.
