“Shall be considered as natural born citizens is a proviso.” Alexander Porter Morse, Treatise on Citizenship
Alexander Porter Morse was NOT a founder. His comments a century later still do not carry the weight of the words of a founder even if he was chronologically closer to them than we are.
The fact is the founders who ratified the Constitution clearly thought it was within the purview of Congress to specify who is and is not a natural born citizen in certain cases. This demolishes opposing legal theories. In particular the accusations that those of us who consider Cruz a natural born citizen are traitors and betrayers of the Constitution. I am in good company even if I am wrong. The founders shared my views.
