Four candidates have taken out nomination papers for two Board of Selectmen seats on the spring election ballot, according to the town clerk’s office. Incumbent Norman Cohen is seeking reelection, while newcomers Saatvik Ahluwalia, Robert Rotberg, and Michelle Ciccolo have started the process of running for the position. Selectman Hank Manz announced in November that he will not seek reelection after nine years on the board, leaving his seat without an incumbent. The top two finishers in the March 3 election will win three-year terms. The deadline for returning the nomination papers, which for selectman must be accompanied by the signatures of at least 50 local registered voters, is Jan. 13 at 5 p.m. For more information on the election process, visit www.lexingtonma.gov.
