http://restoretheconstitutionalrepublic.org has a comment by a Texan who says that he or she recently talked on the phone with Congressman Ron Paul about the meaning of “natural-born” in Article II, for presidential qualification. According to the comment, Paul said, "There is no law that actually defines ‘natural born’, so the argument could go on forever with thousands of different interpretations. The consensus is that he is a U.S. citizen, and therefore eligible."
