What Exactly is a "Natural-Born Citizen"?

___The Naturalization Act of 1790, which is actually the only U.S. statute ever to use the term “natural born citizen”, clearly qualifies Ted Cruz as a natural born citizen. 8 USC § 1401, the relevant current statute, doesn’t use the term, but in no way contradicts the 1790 Act.

___George Washington signed the Act into law. James Madison, the principal author of our Constitution, was also in agreement.
