It is self-evident that if Barack Obama senior is his father that Obama can NOT be a natural born citizen.
Sorry, I have a few other responsibilities that prevent me from spending ALL my time on FR. Self-evident? I'm no lawyer but if someone who is born in the United States but has parents who are both illegal aliens can be considered a citizen, then I don't see how someone born in Hawaii to a woman who was a citizen could not be considered a citizen. Regardless of who his father is.
