do you think he was really born in Hawaii?
If he was born in Hawaii to 2 parents who were not U.S. citizens, does THAT make him a natural born citizen?
Yes. The state of Hawaii's vital records say he was born in Hawaii.
If he was born in Hawaii to 2 parents who were not U.S. citizens, does THAT make him a natural born citizen?
Yes, so long as both parents were residing with the united states and were not protected by diplomatic immunity.
The only cases in which a child born on US soil is not a natural born citizen is if the parents are diplomats, invaders, or travelers in transit who have no intention of residing within the USA.
