Yes. Your point?
My point is that Senator Cruz is a “National and Citizen of the United States
At Birth.”
Here are the qualifications for being a Citizen of the United States At Birth while being born outside of the U.S. to a citizen parent and a non-citizen parent who are married:

Those are NOT the qualifications for being a nationalized citizen. The qualifications for naturalization come under the Immigration and Naturalization Act of 1952. (Which is included in the U.S. Code of Laws).
