It is not a question of citizenship, but of being a ‘natural born citizen’ which is specific language in the constitutional requirement to be POTUS. And as has been written elsewhere there is a difference between a ‘citizen by birth’ and a ‘natural born citizen.’ So significant, in fact, that the Founders who crafted the Constitution put in that very specific term for a very specific reason.
Yes, they meant BORN a citizen, not naturalized.
You could be NATURALIZED and be a senator.
That’s why they put natural born in there, to distinguish that they wanted the president to be BORN in the U.S., but didn’t care if a senator was BORN in any other country on the face of the earth!!!!!!!!!!
