State Rep. Brian Wallace (D-South Boston) is not running for another term, sources tell the Lit Drop.
Wallace, whose district includes a piece of Uphams Corner and Harbor Point, has served in the House since 2003.
The seat is the third in the Dorchester and Mattapan area to open up in the last month. Wallace's retirement ended months of speculation of whether he was running again. It appeared to be recent, too: On his Facebook page, a second signature drive was scheduled for this weekend.
Though Republican Scott Brown won South Boston in the U.S. Senate race, most of the individuals showing interest in the Fourth Suffolk district seat have been Democrats. They include Michael McGee, a South Boston attorney who announced in November that he was running; Jacob Bombard, former president of the student government association at South Boston Harbor Academy; Jeffrey Poreda, a UMass-Boston student; and Mark McGonagle established a political committee with the Office of Campaign and Political Finance.
Accountant Patrick Brennan is running as a Republican.
