Election roundup: Two former rivals endorse Walsh

Arroyo and Barros are on board:

"Throughout my life I have advocated and worked for an inclusive city," said Barros. "We need a Mayor who will not only work to improve our education system, but one that will work to ensure every child has a quality educational seat, one that will work to ensure every resident and neighborhood has opportunity for affordable housing, one that will work to ensure every neighborhood is benefiting from economic development, and ensure that every resident lives in a safe neighborhood. Marty is the candidate that can do that. I am proud to stand next to Marty Walsh and endorse him for Mayor of Boston."

The Herald wonders who gets Charlotte Golar Richie's endorsement. The Ward 4 (South End) Democratic Committee, which backed Golar Richie last time, backs Connolly this time.

Connolly is promising a very special endorsement of his own, 1:30 p.m. in Charlestown. Garrett Quinn reports it's City Councilor Sal LaMattina.

Connolly testified at the State House yesterday for a bill raising the graduation age to 18; he co-sponsored a similar City Council measure in 2011.

James Aloisi writes the Seaport is turning into an undistinguished collection of boring buildings that could be Anywhereville, USA and says the next mayor should do something with the BRA to keep that from continuing.

Wicked Local Roslindale talks to Tim McCarthy and Jean-Claude Sanon, who want to replace Rob Consalvo as District 5 city councilor.
