Wicked Local Brookline’s town election got off to a cold and wet start Tuesday amid a heavy rainstorm, with early voting and mail-in ballots contributing to quiet polling places. Through 7 p.m., the town had seen 6,937 votes cast so far in the May 4 Town Election, including early in-person votes and mail-in ballots tabulated at individual precincts, according to Jeff Nutting, a consultant in the Town Clerk’s office who has led Brookline elections during Town Clerk Pat Ward’s leave. “In person voting today so far is extremely light,” Nutting wrote in an email. “I am not sure if the weather is affecting turnout.”
