“Iâm as much an originalist in constitutional matters as anyone, but the ânatural born citizenâ requirement has really lost a lot of its relevance in an age when international travel and intermarriage between citizens and non-citizens has become so common.”
On the contrary, it has made the issue far more relevant than before, and consideration should be given to extend the prohibition to other governmental positions as was traditional in most legal history before the Constitution. The traditional prohibition against more than one allegiance and more than one nationality or citizenship should also be re-established and enforced. Otherwise, the concept of independent governance and constitutional limitations upon the delegation of powers from a sovereign citizenry is rendered moot.
All of this has taken place under the leadership of "natural born citizens." So I'd say this provision of the U.S. Constitution has done absolutely nothing to protect the citizens of this country from foreign influence.
