“John Jay did not have English common law in mind when he wrote that letter to Washington.”
Of course not. He had in mind a translation of Vattel that would be made 10 years later, right? You’re a mind-reader, and Jay predicted the future...
"John Jay wrote in a letter to George Washington dated 25 Jul 1787:
"Permit me to hint, whether it would be wise and seasonable to provide a strong check to the admission of Foreigners into the administration of our national Government; and to declare expressly that the Commander in Chief of the American army shall not be given to nor devolve on, any but a natural born Citizen. ""
So where does John Jay say "natural born Subject"? No, he does not.
