It is important to remember that Biden "Won" Arizona by less then 11,000 votes.Arizona Senate Report on the Maricopa County Election Audit Highlights 49,000 Questionable Votes, Asks AG to Investigate
Here is a breakdown of those 49,718 questionable votes:
23,344 mail-in ballots were counted from individuals who no longer lived at the address to which the mail-in ballot was sent. The audit called these “mail-in ballots voted from prior address” in the voter history phase. (critical impact)
9,041 more ballots returned by voters than received in the voter history phase. (high impact)
5,295 voters that potentially voted in multiple counties in the certified results phase. (high impact)
3,432 more ballots cast than the list of people who show as having cast a vote. The audit called this group of ballots “official results does not match who voted,” in the certified results phase. (medium impact)
2,592 more duplicates than original ballots in the ballot phase. (medium impact)
2,382 in person voters who had moved out of Maricopa County in the certified results phase. (medium impact)
2,081 voters moved out of state during 29 day preceding election in the voter history phase. (medium impact)
1,551 votes counted in excess of voters who voted in the certified results phase. (medium impact)
Look at the numbers above. They don't prove fraud, but they certainly don't validate the election results either.
