He has produced a birth certificate. Its authenticity is questioned, sure, but it is irrelevant. This is where the birther movement was wrong from the start. The birth certificate is irrelevant, except that it legally establishes who is father was. The real issue is the definition of Natural Born Citizen, and if he qualifies or not given the undisputed fact that his father was not a US citizen at the time of his birth.
