The issue of eligibility for POTUSA is more than just plain/ordinary ‘citizenship’. The Founders explicitly added the requirement for POTUSA to be a ‘natural born citizen’ and they intentionally did this as shown when they only required congresspersons to be just ‘citizens’. All following USA SC decisions are in the original framework set by the Founders.
“The Founders explicitly added the requirement for POTUSA to be a natural born citizen and they intentionally did this as shown when they only required congresspersons to be just citizens.”
Correct. A SENATOR can be a NATURALIZED citizen. The PRESIDENT cannot be a NATURALIZED citizen. The only difference is that the President must have been born in the USA, and be at least 30 years old, and “been fourteen Years a Resident within the United States”.
