Likewise, had his mother been 19 or older, at time of birth, and birth occurred OUTSIDE the United States, Obama would also be a Natural Born Citizen.
Please read the entire thread, you have some homework to do.
Not unless his daddy was a US citizen would he be a “natural born” citizen. His daddy was not a US citizen.
He would have been a citizen at birth, but not necessarily (and IMHO just plain not) a natural born citizen. A citizen to be sure, a citizen at birth even, but not a natural born citizen in the sense of Art II section 1 of the Constitution.
