Here’s an even better paper outlining a 2-parent/citizen standard (I forgot to throw this up last night):
Enough of this English law BS I keep hearing (snopes et al) arguing that parents can be aliens.
Vattel never used the term “Natural Born Citizen”. Anyone who cites Vattel for a definition is ignorant of reality. He didn’t use the term.
10 years after the Constitution was approved, a translation of Vattel translated “indigenes” as NBC. Indigene, then and now, refers to an indigenous person. Nothing to do with NBC.
If the Founders had followed Vattel, they would have required the President to be a “native” or an “indigene”.
