“Does the Constitution define natural born?”
The Constitution does not contain a glossary of ANY of its concepts. If that is the test, then the Constitution is worthless.
The Naturalization Act of 1790, written by the same ones who wrote the Constitution, does define natural born — a person born of citizen parents. It specified that citizenship descends from the father for natural born citizenship. Mere citizenship descended from the father only until the 1930s.
It does no such thing. In fact, it does the opposite of what you claim it does. The words "shall be considered as" create a legal fiction. The 1790 act says that Courts are to pretend that a child born abroad is a NBC.
Which is why law and case precedent is used.
Scouts hasn’t ruled on it.
