Sorry, the Clinton’s had the most intense, state of the art opposition research machine that ever existed. If they couldn’t even prove the he was born in Kenya, then it’s not possible. Occam’s razor.
It doesn’t matter, his foreign father made him a British subject/Kenyan national at birth, no matter where he was born.
He is not a natural born citizen.
The children of foreigners are precisely who the founders were excluding because they themselves are foreigners even if we foolishly also give them citizenship.
