District 7 Councillor Tito Jackson won't be running for mayor, District 5 Councillor Rob Consalvo says he’s in, and a familiar face in Dorchester eyes the shifting landscape and sees opportunities.

The round-up:

-- District 7 Councillor Tito Jackson, who grew up in Grove Hall, will not be a candidate for mayor, a source familiar with the decision tells the Reporter. A Jackson spokeswoman was not immediately available for comment.

-- Consalvo’s camp emails out a statement: "I am running for Mayor because I love the City of Boston and I am prepared and ready to serve all of our neighborhoods. I have a proven record of innovation, leadership, compassion, and a strong commitment to public service. Boston is a great city. But there are ways to make it even greater and to make sure everyone in it benefits from that greatness – and that is what I want to do.” The email notes Consalvo will “formally kick-off his campaign later this month.” Brian Clinton, Consalvo’s chief of staff and a former candidate for Governor’s Council, could be a candidate in a District 5 race to replace Consalvo. Another name that’s being floated: Kelly Bates, the executive director of the Access Strategies Fund and a former member of panel that advised Mayor Thomas Menino on overhauling the city’s school assignment system.

-- City Councillor At-Large John Connolly, who has been running for mayor since the end of February, will be announcing he has the support of public officials representing several areas in his neck of the woods, according to his campaign: District 6 Councillor Matt O’Malley of Jamaica Plain and Roslindale, state Rep. Ed Coppinger (D-West Roxbury) and School Committee member Mary Tamer of West Roxbury.

-- Former District 3 candidate Craig Galvin is looking at running for at-large, but the District 4 seat could be a possibility, too. Galvin now lives in District 4, thanks to the City Council redrawing district boundaries last year. Galvin, who was one of the 7 candidates vying for the open District 3 seat in 2011, says he's looking at “any opportunity to represent the people of this city and the people of this neighborhood.” The current occupant of the D4 seat is Charles Yancey. Elected to the Council in 1983, Yancey is mulling a run for mayor. Michelle Wu, a former campaign aide to U.S. Sen. Elizabeth Warren, is running for at-large and held her formal kick-off on Tuesday. Dan Ryan and Jack Kelly, both of Charlestown, have been eying at-large runs as well. Ryan, an aide to Congressman Michael Capuano who lost a close District 1 race in 2006 to Sal LaMattina, told the Reporter last month that he is keeping his options open.
