To a N. Cape May spouter boldly claiming "Presidents must be born on U.S. soil, or territory" and "If Cruz were president, that would open the door to every child fathered by military personnel, born to local women, who were stationed in a foreign land..." Your hypothetical is already the reality. Second, try reading the Constitution. It actually states in relevant part: "No person except a natural born citizen..." Natural born citizen means regardless of place of birth, born to a U.S. citizen parent.
