“natural born”?
So what does that mean?
What is un-natural????
At the time the Constitution was written, it meant a citizen born on American soil. However, Congress has, through legislation, made a somewhat expanded meaning to include certain people born abroad as well - when certain criteria with respect to the citizenship status of one parent or both are met. In Obama's case, though, if he was born abroad, his parents' status would not have qualified him for citizenship at birth under that legislation.
It would be interesting to see how the man who filed suit in this case will try to prove that Obama was born in Kenya, as he claims. There are unlikely to be written records to that effect available, and any potential witness still alive would probably be living in Kenya and be unlikely to be willing to go to Philadelphia to testify in the case.
