That was one of my first thoughts too, I wonder what the laws say about it.
However, the point is that his mother was a US citizen, therefore, it does not matter if he was born on the moon. He was automatically naturalized at birth by his mother's citizenship, and that makes him a "natural born citizen," as the Constitution requires.
What is really intriguing is that given his mother's legal standing, he still refuses to produce a birth certificate. Why? He has no reason to hide it. It doesn't matter if he was born in Hawaii or anywhere else. The probable reason is that his birth certificate says that his name is "Barry Dunham," not "Barack 0bama," or that the birth certificate says that his father is "unknown." Either way he would be exposed as the fraud we've known him to be all along.
But still, unfortunately, Constitutionally eligible.
Any dumba$$ can figure out zero is hiding something and further any dumba$$ can figure out it probably isn't his college thesis. He has problems being a natural born citizen of the United States of America....which of course any dumba$ can figure out he isn't!
Parentage issues.
