Even if Obama was born in Hawaii, he is still not a natural born citizen.
His foreign national father made him a British subject at birth.
Well, his father might not be who you assume him to be. I don’t think we know whether he was eligible to serve as President. And all those Members of Congress who stayed silent on the matter on the days when the Electoral Votes were counted abrogated their oath to support and defend the Constitution.
Any person born in the US is automatically a US citizen; hence the term ‘anchor baby’.
He was also raised a good part of his life in Indonesia, and so far as I know no record of his VISA has been revealed yet.
The whole point of ‘native born’ is to be raised as a Patrick Henry American.
