I don’t know where Obama was born, but I am certain that “birth certificate” is a FORGERY.
His birth certificate is a red herring.
It does not matter where he was born.
He told us on his “Fight the Smears” website that his foreign national father made him a British subject at birth.
A person is only “naturally” an American when they can not be anything else.
Anyone born of foreign national parents inherits the nationality(ies) of the foreign national parent(s).
Natural born citizen means born here of citizen parents.
