There is no constitutional requirement except for what is spelled out in Article 2 Section 1 and in the 12th Amendment regarding counting the process of electoral collge votes.
I was speaking of the Constitutional requirement that:
“No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President; neither shall any Person be eligible to that Office who shall not have attained to the Age of thirty five Years, and been fourteen Years a Resident within the United States.
That’s a status or “state” issue, one either is or is not a natural born citizen. Congress can’t change it, the individual can’t change it. Not even the sitting VP can change it.
Then it's about time we had one, a SCOTUS decision that is. Congress cannot redefine a Constitutional term of art, because that would constitute a change to the Constitution itself, which they can only initiate through the amendment process.
