Sorry, no matter how many pearl clutchers & soothsayers opine, no matter how many how many texts they quote we have never been here before. When the Constitution was written they believed in common sense. They had no computers, no internet, no electronic data that could be manipulated fraudulently. This is a tangle woven in the present which must be unraveled with common sense according to the absolute requirement for free and fair elections that defines our republic.
The election was subverted. Either the win has to be awarded based upon the votes that can be demonstrated to be valid with the contaminated votes eliminated, new electors need to be chosen by the state legislatures or a new election needs to be held. If Biden did not win after fraudulent votes are eliminated then everything that followed the fraud is null & void. POTUS Trump remains President until a new election.
The certification of fraudulent vote tallies, of electors based on fraudulent tallies, of a President based on fraud has no standing once the fraud is uncovered.
