1) No one has proven that we ever had a President in Office who was not qualified to be in office.
2) If we want to entertain a hypothetical that Chester A. Arthur was a President in Office who was not qualified to be in office, we could, just for grins.
3) Constitutional provisions for President of the United States are affected by Constitutional Amendments, which require 2/3 of the states to approve.
4) Having Chester A. Arthur serve as president is not the same as passing a Constitutional Amendment.
5) So, no, the Constitutional provisions for President of the United States were not affected in any way by having a President in Office who was not qualified to be in office.
Thanks for the rest of your answers...
And with this — “No one has proven that we ever had a President in Office who was not qualified to be in office.”
That seems to be our current problem then, doesn’t it...
