This bill lets cities and towns in Massachusetts choose ranked choice voting for local races, including multi-seat contests. Voters rank candidates; ballots are counted in rounds until winners are picked. If adopted, local preliminaries end, and towns must run voter education. Local rules will cover counting, ties, errors, and write-ins. Adoption can be by ballot, ordinance, or charter, and towns can switch back after 4 years. Expect broader support for winners and fewer spoilers.
