Former State House aide Dan Cullinane beat back two independents and claimed the 12th Suffolk House District seat on Tuesday night.
Cullinane, who has been active in local politics as well as inside City Hall and on Beacon Hill, was the heavy favorite in the race, particularly after winning a three-way Aug. 13 primary. The two independents in the race were Lincoln Larmond of Mattapan and Edmond Romulus of Milton.
The 12th Suffolk House District includes parts of Dorchester, Mattapan, Hyde Park and two precincts in Milton. The seat was once held by former House Speaker Thomas Finneran, a Mattapan Democrat, and until this summer, Linda Dorcena Forry, who won a special election to replace Jack Hart in the state Senate.
