State Senator Thomas McGee was chosen Thursday night to succeed John Walsh as leader of the Massachusetts Democratic Party.
Walsh, who has held the post since 2007, will become executive director of Governor Deval Patrick’s political action committee, the Together PAC.
McGee is the Senate chairman of the Transportation Committee and a member of the Ways and Means Committee. Since 2002 he has represented a North Shore district that includes Lynn, Lynnfield, Marblehead, Nahant, Saugus, and Swampscott.
He has also served as chairman of the Joint Committee on Labor and Workforce Development and the Joint Committee on Veterans and Federal Affairs.
