A friend asked me what I thought, so I responded. This was on Facebook, so it is a little informal:
Whether McCain is a natural-born citizen has been getting press (well, minor press) for years, but it makes sense that the politicos would bring it up now. I think the US Constitution was created to define rights between the federal government, the states, and the people, and giving people rights is one of the big things, so it would make sense that “natural-born” would be interpreted broadly. Also, I just spent a few minutes perusing the INA, and sec. 303(a) says “Any person born in the Canal Zone on or after February 26, 1904, and whether before or after the effective date of this Act, 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.” It seems to me that the distinction between “citizen” and “natural-born citizen” is just citizenship at birth. The courts should (at least I think they should) find that the use of “citizen” in the statute means “natural-born citizen.” There.
