At-large City Councilor John Connolly will formally announce he's running for mayor this morning - at 11 a.m. outside Brighton High School.
The location signals that Connolly, chairman of the council's education committee, will make education the center of his race, in particular, school choice and raising the quality of city schools .
A West Roxbury resident, Connolly, 39, has been on the council since 2007. As an at-large councilor, he has shown he can attract votes across the city, although that didn't much help the last person to challenge Menino  - at-large Councilor Michael Flaherty.
Incumbent Tom Menino has yet to formally say whether he's running for a sixth term. Charles Clemens and Will Dorcena have said they are running.
