Amendment 20: Section 3. ...or if the President elect shall have failed to qualify, then the Vice President elect shall act as President until a President shall have qualified...
The framers of our U.S. Constitution knew that pure democracy was a risky experiment for our new constitutional republic to let the popular vote directly elect the President and Commander-in-Chief of the military. That is explained by them in the Federalist Papers. The framers were afraid that one day due to improper influences someone with divided loyalties or otherwise unqualified per the Constitutional mandates would be selected by the people. Thus the framers put the checking mechanism to the pure popular vote in there with the Electoral College and Congress to be sure only a Consitutional qualified person would ever be sworn in and serve as our President. That is one reason why they created the Electoral College.
We have writing to all our 27 elector delegates asked the NOT to vote for an illegal alien!!!
