Established Fact
During active voting on November 3, 2020, a software update was deployed to the “Sitebooks” – Maricopa County’s electronic poll book system – that resulted in the electronic poll book issuing multiple ballots to a single voter without triggering any alert or requiring supervisor override. A poll worker testified under oath that the update neutralized the system’s primary technical control against double voting. The Sitebooks are the only mechanism that prevents in-person double issuance; their disablement during active voting transformed the poll book from an access-control device into a passive log.
