Dan Cullinane, a Dorchester resident who is a former aide to Representative Marty Walsh, has clinched the special Democratic primary in the 12th Suffolk House District, beating out two other Democrats Tuesday.
Cullinane will now face off against two independents, Mattapan resident Lincoln Larmond and Milton resident Edmond Romulus, in a special general election set for September 10.
The seat, which was previously held by now State Senator Linda Dorcena Forry, represents portions of Dorchester, Mattapan, Milton, and Hyde Park.
According to unofficial election results released by the city of Boston, Cullinane took 60.39 percent of the 2272 votes cast by Democrats Tuesday. In Milton, Cullinane took 78 percent of the 373 votes cast by Democrats, according to Milton’s Town Clerk.
Turnout in both Milton and Boston was extremely low with only 10.58 percent of registered voters casting ballots in Boston and 9.7 percent of registered voters casting ballots in Milton.
The two other Democrats running for the seat were Dorchester resident Marydith Tuitt, an aide to Representative Gloria Fox, and Dorchester resident Stephanie Everett, a former aide to State Senator Sonia Chang-Diaz.
There were no Republicans running for the seat.
Everett took 21.74 percent of the vote in Boston and 12 percent of the vote in Milton. Tuitt took 14.26 percent of the vote in Boston and 7.7 percent of the vote in Milton.
Dorcena Forry, a Dorchester Democrat, held the seat from 2005 to 2013. Before Dorcena Forry, the seat was held by Mattapan Democrat and former House Speaker Thomas Finneran from 1994 to 2004.
