FAIRFIELD — The town revised its unofficial election results Wednesday after determining that absentee municipal votes were accidentally excluded from the Election Day tally.

The thumb drive that contained absentee ballots for the municipal election was not placed in the tabulator, Brittanee Guerette, town clerk, said in an email midday Wednesday afternoon.

The error was caught Wednesday when town officials noticed that the presidential election totals and municipal election totals were off by about 1,000 votes. Later Wednesday, the tabulator counted the municipal absentee ballots, originally processed on Oct. 31, and found the difference to be 1,110.

The moment town officials realized the error, they notified the candidates and invited the public to Wednesday’s tallying, which was attended by the chief of police, a Republican ballot clerk and a Democratic ballot clerk, said Michelle Flewelling, town manager.

“We made sure that it stayed open to the public, that all the candidates were informed, everyone was aware, and got it publicized as much as we possibly could, because we do thoroughly respect the fact that ballots must be tallied in the public eye,” Flewelling said.

The results showed that no outcomes were changed as a result, but some margins were narrowed.

According to the updated unofficial results, Matthew Tulley won the seat for the two-year term, while Matthew Townsend and Timothy Martin won the seats for the three-year terms. Tulley defeated Kevin Kitchin, 1,549-1,454; while Townsend had 2,044 and Martin had 1,144, defeating Casey Begin, 821; Kerry Parkhurst Hekl, 643; and Ronald Mclaggan, 438.

The absentee ballots were tallied and added at a 3:30 p.m. public meeting Wednesday at the Fairfield Community Center.

“Just so everyone can see, this machine is empty,” said Brittanee Guerette, motioning to the dark interior of the ballot tabulator with an exaggerated sweep of her hand.

A few attendees peeked their head to check; most laughed.
