re: SCOTUS oral arguments on Trump vs Colorado

The word President was there originally and was intentionally removed. The President has a separate Oath of Office and is the Executive head ....not a lowly officer.

The writers of the Amendment saw to it that the President would never be considered ....

The problem with the assessment some law school clerk made for you? SCOTUS has dozens working for them and their task is to discover everything from the Amendment to the writings of the authors and what was intended. They don't do this in the dark.
