Even more senseless when you consider that McCain was born in the Panama Canal Zone, which was then under U.S. Administration. One may as well argue that William Henry Harrison and all presidents before him were ineligible for election because they were born in British Colonies.
I agree with the first clause of the sentence, but not the second. The Constitution is explicit in the requirement that the president be a native-born citizen or a citizen at the time of the adoption of this Constitution. That is not a matter of judicial interpretation. It is black-letter law.
