Not sure why this is called a birther case. I didn't see in the little bit you offered where it is questioned the place Obama was born. I guess any critique of Obama is now being written off as birther stuff.
But the fact is the he did live over seas under an assumed name for many years.
Truth is he is keeping all his records sealed, why? My opinion, he lied about where he was born. Snopes says he didn't receive a Fulbright scholarship but that doesn't mean he didn't benefit otherwise or maybe it was just that he wanted to be like his daddy.
Truth is it is hard to explain how he got into Harvard considering his younger years drug use and performance.
Something is going on with the SS number thing although snopes writes it off, very much like his bio stating Kenyan birth, to a typographical error. So many people making mistakes concerning one man, what are the odds?

From the following linked article: Snopes concludes that "the most likely explanation" is a "simple clerical or typographical error." Obama, they contend, lived in the Hawaii zip code of 96814, while the zip code for Danbury, CT is 06814. As it happens, "clerical error" is the same excuse used to explain away Obama's claim to a Kenyan birth in his literary agent's 1991 promotional piece.
