So, how would you sort out the claim of a McCain vs, say, Cruz? Other than by holding a national election and counting the votes?
If you want to do it in court, with any legitimacy, you need a bright line.
Schwarzenegger, Austrian born, nope! McCain, military brat, he's qualified! Zero, born in Hawaii, only in America! It's up to the Sheeple!
Bottom line: you can't count on the Constitution to prevent electing an anti-American president.
Cruz is obviously not Natural Born. But he could get away with it if he hires Obama’s lawyers. I really believe that Cruz would represent my beliefs more than any of the others. But he is not an NBC.
