You asked whose job it is to enforce the provisions of the 20th Amendment regarding whether the President-elect has qualified. I answered that question. There was nothing more intended.
No, troll. You mentioned Congress in the process of certifying the electoral vote to come up with a “President elect”.
The one who enforces the 20th Amendment in the event that the “President elect” (the one ALREADY certified as the electoral winner by Congress) fails to qualify by Jan 20th has to do so AFTER Congress is done. (If Congress had found that the candidate failed to qualify because of the objection process you describe, they would never have certified him as the electoral winner, and there thus would never BE a “President elect” who still failed to qualify by Jan 20th.)
And nobody on here or anywhere else has said who that would have to be. This question should be easy, guys. What’s your problem, that you can’t answer it?
