If he had anything, he'd show it.
Actually, this is the first proof I’ve seen that 0bama’s parents were actually married, since there were no marriage records that have surfaced. This is also important, because now if it turns out that 0bama was born in Kenya (or anywhere except in the US) he is not a US citizen. If his parents were not married, that would likely not be the case (except for the age of his mother).
Plus, the name his mother used is significant since it has apparently made finding other stuff easier.
DIdn’t you read any of this on this thread? It’s all there.
