Take a Memo:
please point me to a precedent for a vice or presidential candidate, since those are the only two jobs to require such a thing (a definition or proclamation of natural born). nice try though.
The 1790 Naturalization Act: "children of citizens of the United States that may be born beyond Sea, or out of the limits of the United States, shall be considered as natural born Citizens."
I think this is probably as close as you'll get to a definitive legal precedent for "natural born" citizen. It is an ambiguous term, that's why it continues to be such an issue. If there were some place in the Constitution where it clearly defined "natural born" it hardly seems we'd ever have these long, drawn-out debates. So it's not a cut-and-dry matter and the SCOTUS has never ruled on it.... but, that in of itself is a remarkable testament worth considering... in our 240 years, the high court has never been compelled to rule specifically on this issue.
That may largely be due to the fact the court doesn't involve itself with "political questions." If things come before the court as a matter of political question, they defer to political process (the will of the people) and reject hearing the case.
