Vattel’s Law of Nations is not United States Law, which I quote.
The reason Barry Goldwater was eligible to be President is that the Arizona Territory, in which he was born, was an incorporated territory, and expected to fully become part of the United States. (There was a major fight within the Republican Party over this issue. Gov.George Romney was born in Mexico with citizenship derived from his U.S. citizen parents but he was not an NBC. His son made it a point to emphasize his eligibility in 2012.)
The Panama Canal Zone, from the very beginning, was an unincorporated territory (same goes for Puerto Rico and Guam). We leased the land containing the Canal Zone from Panama - they never signed away national sovereignty to that land. Today it is completely Panamanian.
People born in The Panama Canal Zone, like those of Puerto Rico and Guam, are recognized as statutory U.S. citizens courtesy of the U.S.Congress, but they are not Natural born Citizens.
(See Wikipedia for details.)
Because Puerto Ricans are U.S. citizens, if they migrate to the U.S. mainland, any children born within the United States proper, I believe, are considered Natural born Citizens but not those born on the island of Puerto Rico.
Hey! I don’t make the laws! I’m just reporting what I’ve found.
Incidently, Sen.John S. McCain accepted over $100,000 in donations from George Soros during the 2008 election.
My point is simple. "Natural born citizen" is either based on Vattel or it is not. If it is, then Vattel's definition for the children of service members applies.
You can either have Vattel, or you cannot. You can't have half Vattel, and Half English Common law.
