John F. Barros resigned from the Boston School Committee this week because he says he is seriously considering a run for mayor, taking another step toward jumping into an already crowded race.
Barros stopped short Tuesday of declaring his candidacy, saying in an interview he had “not formally made that decision.” Last week, Barros formed a candidate’s committee with the state Office of Campaign & Political Finance, a move that allows him to raise money for a campaign.
On Monday, Barros submitted a letter of resignation to Mayor Thomas M. Menino, saying he would immediately leave his post on the School Committee because he did not want his political activity to compromise that board’s work.
“The School Committee’s work should not be political, and the integrity of the work of the committee will be threatened if political interest is perceived to influence decisions in any way,” Barros wrote.
Barros’s resignation was first reported by the Dorchester Reporter. In the letter, Barros said he was proud of his 3 ½ years on the School Committee and described Menino as a “true education mayor” who has “overseen the transformation of our system into a higher performing urban district.”
Barros was the first Cape Verdean to serve on the School Committee when he was appointed in January 2010. In the interview Tuesday, he said he has been asking for people’s support and examining whether he can raise enough money to mount a campaign.
Barros, a Roxbury resident and executive director of the Dudley Street Neighborhood Initiative, would join a field of potential candidates that has almost grown to two dozen. A flood of aspiring mayors have stepped forward since Menino announced he would not seek a sixth term.
Another candidate, Bill Walczak, loaned his campaign $50,000 to jump-start the effort. Walczak, a co-founder of the Codman Square Health Center, is a first-time candidate and began his fund-raising from scratch.
“Obviously, I’m committed to my campaign,” said Walczak, who has also deposited $6,800 in donations. “I started with zero.” Andrew Ryan can be reached at email@example.com Follow him on Twitter @globeandrewryan.
