The succession is spelled out in simple plain English, it goes President, Vice President, Speaker of the House, Secretary of State.
Only in fantasyland would there be a ‘do over’ election, grabbing the VPOTUS of the last administration, or certifying the losing candidate and their VP as the new administration.
Once again, this is the United States of America, where we need to follow the Constitution; not “make it up as you go along Land”.
Still does not answer my question when was Succession settled ANd when was it first proposed?
