“Should we consider the mothers of President’s who became citizens via marriage to have been natural born citizens?”
No Presidents have become citizens via marriage, and any such citizenship would not modify the citizenship of the mother.
If you intend to ask, “Should we consider the child of a woman who became a citizen via marriage a “natural born citizen”, then the answer is “yes, of course”.
O.K., that’s all I wanted to know, thanks! I guess some statutes DO matter in determining natural born citizenship.
