He is a natural born citizen per Article 1 section 8 which vests Congress with the authority of making the rules of naturalization. Which they have codified in Title 8 Section 1401 subsection G that stipulates that Mr Cruz is a citizen at birth and thus has never needed naturalization.

Do you realize that you just said he is a citizen under the Authority of Congress to make the rules of Naturalization?

If Congress uses their powers of naturalization to make him a citizen, then he is defacto a "naturalized" citizen. Actually, this is exactly what the Supreme Court held in Rogers v Bellei.

Bellei was a naturalized citizen, and so is Cruz. They were naturalized before birth, en masse, and in accordance with a statute passed by Congress which has the authority to do so under the "naturalization" article you cited above.

Thanks for the link to the Supreme Court opinion.
