Well..........they sure differentiated between "Natural Born Citizen" and "plain old Citizen" regarding presidential requirements. What do you think they meant?
The fact that folks in the late 18th century understood what the term meant.....is not even a debatable issue.
They never used “plain ole citizen” so you are making a straw argument. What they clearly meant was to keep folks who have divided loyatlies from becoming President, and that is the ONLY thing beyond debate. They clearly were NOT trying to single out folks like Cruz for ineligibilty....
