No it would not change my mind if it was sent by senate/legislature leaders acting in their individual capacity.
What might change my mind is if it had been an official act of the legislative body, passed by vote according to the rules of that legislative body, and which that the legislative body had the constitutional and statutory authority to take.
The Eastman memo is evidence of an attempt to overturn the election and, re: competing body of electors, it fails at all three steps of that analysis. That’s an attempted coup.
Regarding the audits: It seems like a propaganda effort to grease the skids for the next attempted coup. If they are being done for any other purpose, then they are being handled in a way that is imprudent. I do not have any reason to think they are either illegal or unconstitutional.
