Plus - when he was allegedly born (I still think he’s an alien from another galaxy), at least one parent had to have been a US citizen for at least 10 years, 5 of which had to after the person was 16.
Obama’s alleged momma was 18 (IIRC) when he was allegedly born, so the question must be asked: where was SHE born?
That was debunked on a previous thread: the “5 years after age 16” residency rule for a parent applied only when the child was born outside the U.S.
