What is your legal and/or constitutional basis for this conclusion?
Is there a third category of citizenship? I.e.,
Obama is natural born, unless it is shown he was born outside the US, and the law about his mother having to have lived five years past the age of 14 in the US is upheld.
McCain is also natural born, having been born to two US citizens. The stuff about whether he was born on the naval base and whether the base was US soil is irrelevant. They could have had him on the moon, and he'd still be a natural born citizen.
