And here's 8 USC 1403 which covers those born in the Canal Zone or the Republic of Panama on or after 1904:

§ 1403. Persons born in the Canal Zone or Republic of Panama on or after February 26, 1904

(a) Any person born in the Canal Zone on or after February 26, 1904, and whether before or after the effective date of this chapter, whose father or mother or both at the time of the birth of such person was or is a citizen of the United States, is declared to be a citizen of the United States.

(b) Any person born in the Republic of Panama on or after February 26, 1904, and whether before or after the effective date of this chapter, whose father or mother or both at the time of the birth of such person was or is a citizen of the United States employed by the Government of the United States or by the Panama Railroad Company, or its successor in title, is declared to be a citizen of the United States.

Doesn't say anything about "natural born." Just says they're a citizen of the United States. A person who is naturalized is also a "citizen of the United States."

Well, was McCain a citizen at birth, or wasn’t he...? You’ve repeatedly stated that there were only two ways to become a citizen : by birth or by naturalization.
