Here is Schlafly in 2004:
The extensive litigation concerning American Indians illustrates that consent rather than place of birth is what controls citizenship. Indians did not receive citizenship until conferred by congressional acts in 1887, 1901 and 1924, long after ratification of the Fourteenth Amendment.
The Constitution states that "no person except a natural born citizen" is eligible to be President. Everyone recognizes that this provision disqualifies the Governors of California and Michigan who were born in Austria and Canada, respectively.
On the other hand, then Michigan Governor George Romney, whose birthplace was Mexico, ran for president in 1968, and Senator John McCain, whose birthplace was the Panama Canal Zone, ran for president in 2000. Both were "natural born citizens" because their parents were U.S. citizens and subject to the jurisdiction of American sovereignty.
It's not the physical location of birth that defines citizenship, but whether your parents are citizens, and the express or implied consent to jurisdiction of the sovereign.
