Abington residents elected a new selectman last Saturday and reelected another, and approved a $780,000 feasibility study for a new middle school. School Committee member Tom Dion finished second in the selectmen’s race in a battle for two openings, defeating incumbent Chris Aiello by about 300 votes. Vice chairman R. Andrew Burbine was returned to office, finishing with the most votes. Kathleen Bailey and Michael Kurowski won seats on the School Committee, with votes of 1,560 and 1,216, respectively, and Patricia Donnell lost with 982 votes. The $780,000 feasibility study for a new middle school was approved with a vote of 1,213 to 856. The town is expected to pay, in all, an estimated $340,000 after reimbursement of $440,000 by the Massachusetts School Building Authority. About 22% of registered voters participated in the April 28 election, a typical turnout for a local election, according to town clerk Linda Adams.
