Was a voting system used in multiple states including Wisconsin responsible for a vote-tally inaccuracy in Michigan during the 2020 election?

Both the Michigan State Department and an independent investigation found that Antrim County's inaccurate vote tally was the result of human errors, and not a malfunction or manipulation of Dominion Voting Systems' election equipment.

The department stated that prior to the election, the county's clerk accidentally did not update software used to collect voting machine data. This caused the results not to be combined properly despite the tabulators having counted the ballots correctly.

The subsequent investigation clarified that multiple memory cards "had not been updated after the ballot design changes," causing staff to misinterpret the data and misattribute votes.

A few hours after reporting unofficial results that favored Joe Biden, the county discovered the errors and retracted them. The revised results, reported days later, awarded Donald Trump the county.

The investigation concluded that the incident "was initiated by unusual circumstances that are unlikely to have widely affected other jurisdictions."
