Voting is underway to fill two vacant seats in the Massachusetts Senate.
Republican Patrick O'Connor and Democrat Joan Meschino are vying in Tuesday's special election in a South Shore district that was represented by Republican Robert Hedlund until his election as mayor of Weymouth in November.
O'Connor is president of the Weymouth Town Council and served as Hedlund's legislative director.
The latest news from around the state
Meschino is an attorney and former selectwoman in Hull.
The race to succeed East Boston Democrat Anthony Petruccelli, who left the Senate to join a lobbying firm, was essentially decided last month when Joseph Boncore of Winthrop won a crowded Democratic primary. There is no Republican on Tuesday's special election ballot.
Republicans currently hold only five of the 40 seats in the Massachusetts Senate.
