A youth movement to allow 17-year-olds the right to vote in city elections took a step forward recently when the measure won approval in the Massachusetts Senate. The United Teen Equality Youth Center’s Vote-17 campaign began in 2009 with a youth-led City Council forum. Now the proposed measure is part of an election modernization package in the Senate. If Governor Deval Patrick signs off on the full package, the next step will be a vote by Lowell residents to determine whether 17-year-olds can take part in city elections. Teens involved in the movement throughout the years have raised awareness by holding fund-raisers, petitioning the State House, and going door to door to rally residents to their cause.
