The League of Women Voters of Brookline is co-sponsoring a workshop Wednesday to teach people how to run for local office. The workshop will also discuss the duties of local elected officials, from selectmen and School Committee members to Town Meeting members. Speakers will include Town Clerk Pat Ward, Selectman Ken Goldstein, and School Committee member Abby Cox. School Committee member Barbara Scotto will moderate the workshop. This year’s town election on May 6 will elect two selectmen, three School Committee members, four library trustees, a member of the Board of Commissioners of the Brookline Housing Authority, and Town Meeting members. Brookline’s Sara K. Wallace Fund for Voter Education is also co-sponsoring the workshop with the Brookline Neighborhood Alliance and the Town Meeting Members Association. It will run from 7 to 9 p.m. in room 103 at Brookline Town Hall.
