In the 2008 election both major parties nominated candidates whose eligibility is dubious. For Barack Obama the question was whether he was born in Hawaii, which is U.S. soil. For John McCain the question was whether the Panama Canal Zone, where he was born, was U.S. soil. It is not, and being born of parents both of whom were U.S. citizens did not make him a "natural-born" citizen, although a statute was later adopted naturalizing such persons at birth.
