Well......I have a football game to listen to and will be distracted thankfully for a while..
To sum up, in my view the natural born language was meant to include all those who were not citizens of the 13 colonies at the time but were born on the continent, like the American Indian for example. They had no citizenship and were not citizens at the time of enactment.
Hamilton’s original draft nor the approved amendment language was related to Vattel or anything else.
The original draft language read this way;
“”No person shall be eligible to the office of President of the United States unless he be now a Citizen of one of the States, or hereafter be born a Citizen of the United States.”
So simple.....
This left congress to determine who a citizen is. As it should be.
But the final draft muddled the language yet appears to mean exactly the same thing. Yet the term natural Born was used, and I think this was used to include those who currently held no state citizenship yet needed to be legalized.
I'm watching the game too, sort of.
The Indians were NOT made citizens of the US. They were citizens of their own nations. This was a deliberate exclusion.
-- This left congress to determine who a citizen is. As it should be. --
As it is. Congress absolutely has that power. What the constitution aims to cut off is congressional power to expand the pool of presidents via acts of naturalization. There are two ways an "invader" could obtain qualification. One would be your Mexican invader example, born on US soil; the other being a Congress that was liberal with regard to naturalization of birth abroad.
The principles at work are highly nationalistic. As national barriers are broken down, and nations merge into "one world," all that nationalistic stuff can go in the crapper.
