Kudos, sir. You have identified the exact Constitutional clause that should void these elections. The only Constitutional way to force the election-thieves out of office, is a successful SCOTUS challenge with PROOF of election fraud. We need to produce that proof in order to secure wins here.
There’s a little problem with this. The Constitution makes no mention of individual citizens voting in a popular election for president. The votes were duly cast by Electors, counted, and recorded, as per the Constitution.
Remember when Trump wanted some state legislatures to appoint Electors that would vote for him rather than according to the popular vote count?
Had he succeeded in getting enough Electors to win, no matter the popular vote, he would have been legally and duly elected president in accordance with the Constitution. Only he did not succeed. The votes were cast by the Electors, counted, recorded, and Biden was inaugurated. Too late now. No court is going to entertain this, nor should it.
