Nice strawman, but I have a feeling had Obama's papa become a U.S. citizen and Obama not moved to Indonesia with his second foreign father, skeptics wouldn't care so much. "Natural born" refers to the characterization of one's citizenship, similar to being a "natural born athlete," "natural born musician" or in Obama's case, a "natural born liar" ... meaning that you acquire the trait naturally. With two foreign nationals for father's and a mother who promptly moved out of the United States, Obama has no direct, natural influence from which to become a natural born U.S. citizen. Had his parents stayed together, he might just as easily be the president of Kenya today. His best claim now is because his mother kicked him out of Indonesia to go live with his grandparents. Natural born doesn't result from skipped generations.
Wait a sec. Are you suggesting that a child born to the non-citzen father is not a natural born at the time of birth, but then somehow magically becomes a natural born citizen when his father subsequently naturalizes?
Do you have anything to support this novel legal theory of yours?
