New candidate Aaron Dushku collected the most votes in the race for four at-large positions on the Town Council in Tuesday’s municipal election. Incumbent John Donohue was among the candidates who fell short in the eight-way contest, according to unofficial results from the town clerk’s office. Mark Sideris, the incumbent Town Council president, was reelected with 67 percent of the vote, defeating Clyde Younger, a former council president. In the at-large council race, Dushku received 16.5 percent of the vote, ahead of three incumbents — Anthony Palomba, with 15.4 percent; Susan Falkoff, with 15.3 percent, and Stephen Corbett, 13.5 percent — who were returned to the board. Corbett had a 40-vote edge on Donohue, who tallied 13.2 percent. The School Committee will also see some fresh faces. While incumbent John Portz won 24 percent of the votes, the most of any candidate, newcomers Guido Guidotti and Elizabeth Yusem are taking the other two seats on the ballot, with 17.9 percent and 17.7 percent, respectively. The Town Council’s district representatives will stay the same, as all four incumbents — Angeline Kounelis, Cecilia Lenk, Vincent Piccirilli Jr., and Kenneth Woodland — ran unopposed. The Watertown Free Public Library’s board of trustees will also get a new member in Carol Tierney, who will fill a vacant seat. Incumbents Raya Stern and Gracemarie LeBlanc were returned with no competition. The clerk reported the turnout at 21.3 percent of Watertown’s 22,481 registered voters.
