Natural born, for the purposes of being president, cannot be changed by Congress.
The ONLY way the Natural born Canadian Crus Liar gets the nomination is by selling his soul to the establishment. OH WAIT... that already happened!!!
Sure it can. It has been changed by Congress. See Obama. Not a peep about the qualifications (or lack thereof) associated with dual citizenship at birth.
That’s my opinion too. It was not defined in the Constitution. The definition could be proposed as a Constitutional Amendment, and duly ratified.
Congress has powers pertaining to uniform rules for naturalization. Naturalization does not pertain to natural born citizens-hence not within Congress’s jurisdiction.
