The US Constitution was written by men knowledgeable and strongly influenced by Vattel’s Law of Nations. The Law of Nations is the source of Natural Born Citizen and Cruz does NOT qualify!
Ted Cruz’s mother was British, wasn’t she?
The US Constitution is NOT defendant on Vattel. In fact, the very first naturalization act passed by the very knowledgeable men you referenced, SPECIFICALLY contradicted Vattel by making their own definition of NBC.
