States are talking, planning to DECERTIFY Electors.
That is not to say that a showing that the election results were significantly wrong could not have political effect, but the 2020 Presidential election from a legal point of view is done, and Biden has been confirmed by Congress and installed as President.
Anyone can think and write from basic process rudiments what you wrote but it would be incomplete if not short-sighted.
Decertifying Electors who have already voted in the EC is as you maybe meant to write not an actionable or valid claim for reversing the EC vote for 2020.
But that’s not what decertification is intended to do, it is not intended to reverse the EC.
Decertification is an endpoint act from irrefutable evidence and proof determining malfeasance, fraud and error. It can be followed by certifying the true results of 2020 elections. Decertification is a component of certifying the true results.
When the mountain of evidence and proof is attached to a state legislature’s decertification and corrective certification, then it becomes material to any court action taken to remedy an error. One fo those actions is a process known as QUO WARRANTO.
