Editor’s note: The town of Windham, New Hampshire, is presently conducting an audit of its Nov. 3, 2020 election, in which a hand recount one week later revealed that four Republican candidates each gained about 300 votes not counted on Election Night. Vermont uses the same Diebold AccuVote-OS vote tabulators owned by Dominion and managed by LHS Associates, of Salem, N.H.
Over the weekend, two auditors of the Nov. 3 election in Windham, New Hampshire, discussed an AccuVote tabulator glitch that produced errors based on ballot folds.
“So the question here was, would the fold through [candidate] St. Laurent’s vote target be interpreted as a mark that would generate an overvote in that contest so that none of the four would be counted. And we found rates of generating overvotes from roughly 24 percent up to 72 percent,” auditor Philip Stark told interviewer Nick Moseder.
The folding issue is not the only problem, auditor and computer expert Harri Hursti tweeted Sunday night. Error rates are another suspicious issue for the tabulator machines.
To clarify: The work is not completed yet. While the folding seems to be a strong contributor it clearly is not the only factor. For example: We have observed vastly different error rates on two machines processing the same ballots. Work continues. @WAuditors #ElectionSecurity
