See what that guy who is suing is trying to say is that he was either born in Kenya, but then his mother listed him as being born in Hawaii. That he became a citizen of Indoneasia when his mother married a citizen there, and that he had mentioning going to school in Kenya or something like that, basically claiming that the mother who was american gave up her right when she went to both Kenya and Indoneasia and never did either him or his mother re-take the oath in the U.S. or something to that effect.
The problem with that is, that they can not prove that his mother gave up her U.S citizenship when she got married. Nor that he was born in any other place then Hawaii, no hospital will confirm this because Medical records are confidental. Like I said all these people and its more then just this guy are either doing it for attention or trying to cause trouble. The fact that people are buying it and not doing research themselves is reall sad. I mean look at McCain when it was said he was born in the Panama Canal, but due to circumstances he is considered a US citizen.
I don't know what they think they are proving but I really wish they would just drop it, I admit our government can drop the ball, be loopy and down right dumb at times, but even I don't think they would let Obama run for Senate, or even President if they didn't infact know exactly where he was born, where he traveled, and what he ate for breakfest on his tenth birthday lol.
