There is no “decertification”. That ship sailed in December. There is zero Constitutional basis to what you are proposing, and it 100% isn’t going to happen. Any amount of audits and recounts can only serve to secure future elections, by State legislatures enacting rules for 2022 and beyond.

What is the path forward if a State de-certifies?
You you got that path locked?
