I’ve skimmed the report (Maricopa County Forensic Audit Volume III: Result Details) and don’t see where there is a breakout of how the “57,734 ballots with serious issues” broke out by candidate. Only then can we tell if the bad ballot swayed the election to Biden.
It is a fair point, but I would not be surprised if the bad ballots break for Biden at around 95%.
I think the cyber ninjas know which way the bad ballots broke.
