Let Harvard Law to explain it to you. According to them, Obama & Jindal are not natural born citizens per the 14th Amendment.
There is a supreme court case from the 70’s/80’s regarding the right of citizenship to children borne from soldiers in Vietnam’s relations with native women. The ruling was that while obviously a child borne to an American woman overseas was a citizen (didn’t mention “natural born”, but didn’t need to), for the child to claim his paternity granted citizenship, paternity had to be established. The notion that the child of an American woman born while she happened to be next door in Canada is ineligible to be President is nonsense.
