Maybe you should check the law. The law, even before 1986, works along a pathway.
First, were you born in the U.S. to parents who did not have diplomatic immunity? If yes, you are a natural born U.S. citizen.
Second, were you born outside the U.S. to parents that were both U.S. citizens? If yes, you are a natural born U.S. citizen.
Third, were you born outside the U.S. to a parent that was a natural born U.S. citizen and to a parent that was a not a citizen? If yes, you are a natural born U.S. citizen.
Fourth, were you born outside the U.S. to a parent that was a naturalized U.S. citizen that had lived 10 years in the U.S. including five years past the age of 16 and to a parent that was not a citizen? If yes, you are a natural born U.S. citizen.
Since Obama qualified under the first check point, the rest is irrelevant.
Even if Obama had been born in an airplane toilet somewhere over the South Pacific, he would have been a natural born U.S. citizen.
The noise to signal ratio at this forum is growing.
