Bottom line is this.... If the framers meant native born they would have used that term, they didn’t, they used natural born. Unfortunately other than the Naturalization Act of 1790, which was superceded, it was never defined again.
This is where deep constitutional fundamentalists haul out Vattel’s Law Of Nations and say aha, it furnishes us with a definition.
Maybe they didn't see a reason to define something so obvious.
The natural born citizen concept isn't new and has similar application and use in property law and inheritance.
Oh well...they did their best, but they never counted on kids like US in times like these.
I believe that even the Founding Fathers themselves wouldn't have standing to challenge a candidate's eligibility in our courts today, not in 2016's Amerika, and they wrote the Constitution!

It wasn't just superceded, the 1790 Act was actually repealed. The 1795 Act specifically states such.
