Where does the Constitution do that? Not Vattel. Not British Common Law. But where does the Constitution itself define natural born citizen?
You're right; I apologise for the mistake. I meant that the Constitution does show that Madison et al did show, by the phrasing they used, that they intended to show that there is a distinction based on Vattel's 'Law of Nations' Chapter XIX Section 212 - to wit:
As we found out from our last Impeached President, it does appear that some lawyers can be educated beyond their intelligence - otherwise every jot and tittle would require a dictionary definition included in the documentation.
As I said: There are only five instances in the Constitution detailing "citizen". Only ONE has any specified qualification: they made a clear distinction between "natural born citizen" and "citizen" in this clause. That phrase only leads to Vattel for its base determination.
