A revote in the Bridgehampton Fire District’s commissioner race has been scheduled for next month after the district found that two people who were no longer residents of the district had cast ballots.With 175 votes on paper ballots there was a tie between Philip Cammann and John O’Brien, but once write-in votes were counted, the vote went in Mr. O’Brien’s favor. However, because there was no legal certainty as to whom the two nondistrict residents voted for and such a small margin separated the candidates, a revote will be held.“We chose Jan. 20 because we all felt we would obtain the greatest participation and because the law prohibits a vote on less than 27 days notice and requires it to be on a Tuesday,” Brad Pinskey, the fire district’s lawyer said by email. “Both candidates approved the date.”
