A son of US Representative Michael E. Capuano said today he is mulling a bid for the state House of Representatives.

But if he gets in the race, he’s likely to be part of a crowded and competitive Democratic field to succeed state Representative Carl M. Sciortino, an outspoken liberal who recently announced he was leaving his Medford- and Somerville-based seat on Friday to lead a nonprofit advocacy organization.

Lobbyist and political consultant Joseph Capuano, 30, said he was pondering a run and would decide on whether to jump in by the end of the week. “It’s not every day that there’s an open representative seat where I live,” he said.

Capuano, of Somerville, ran unsucessfully for alderman in the city in November. Politics, he said, “it’s in my blood.”

Brian S. McNiff, a spokesman for the secretary of state said four Democrats had pulled papers to gather signatures to qualify for a run for the seat. They are Taylor J. Barnard, Craig E. Rourke, Sharon Guzik, and Christine P. Barber. The district—the 34th Middlesex—is heavily Democratic.

Barnard, a 22-year-old Tufts University senior and the national president of College Democrats of America, said he was “giving a strong look at the race.” Barnard, of Medford, said he believed he could follow in Sciortino’s footsteps and “be a strong champion for the community.”

Rourke, a 35-year-old lawyer and Somerville resident, said he was getting in the race to “fight hard for hardworking folks” and had already been out on the campaign trail listening to local residents’ concerns.

Guzik, 52 and of Medford, and a former member of the school committee, said she was seriously looking at a run. An activist, she said she would like to be the person to carry on Sciortino’s work in the State House and is particularly passionate about education and libraries.

Barber, a 37-year-old policy analyst at a health care nonprofit, said she was definitely running. A Somerville resident, she praised the current representative and said she wanted to continue “progressive leadership for Somerville and Medford.”

Among the other people who said they are considering a run in the Democratic primary: state house aides Sean J. Fitzgerald, 51 and of Somerville and Peter Antonellis, 33 and of Medford.

Sciortino, for his part, said he had been answering questions from potential candidates and “would be not as inclined to endorse if I had multiple friends running.”

Even though Sciortino will leave the State House this week, the state will not hold a special election to fill the vacancy, according to a spokesman for House Speaker Robert A. DeLeo.

“Given the proximity of the April 29 signature filing deadline, cost-pressures on municipalities and his discussion with Secretary Galvin, Speaker DeLeo believes no further special elections should be held during this election cycle,” Seth Gitell said in a statement.

The primary for this race will be held on the state’s traditional primary day in September.
