I doubt the Founders thought exceptions had to be made. If they had, they wouldn't have used the term natural born. they would have just said citizen.
Natural born HAS been clearly defined and has been for over a hundred years. Someone is natural born because they have nothing else to choose from. Born in a country of parents who are its citizens. I learned it in high school civics class. I've seen other FReepers say they did as well.
And nothing I've learned since has contradicted it.
“I doubt the Founders thought exceptions had to be made. If they had, they wouldn’t have used the term natural born. they would have just said citizen:
What you posted to me from Vattel contradicts what you just said. That’s the problem with your argument, if they valued what Vattel said then they considered exceptions.
As for your shouting that Natural Born has been clearly defined, please cite all the cases which meet the criteria unique to this case, that are settled law
