Fifteen days to Sept. 24. Most candidates have back-to-back forums on their plates tonight: First up is a forum focusing on arts and culture. That forum starts at 6 p.m. at the Paramount Theatre. Then they walk down the street to the Modern Theatre for an 8 p.m. forum put together by New England Cable News, the Boston Herald, and Suffolk University. The Herald offers tips on how to tune in here. Codman Square Health Center co-founder Bill Walczak plans to be aggressive, noting that the debate is televised. (He has an ad, too.)

THE DAY AHEAD: City Councillor At-Large Felix Arroyo visits the Twelfth Baptist Church Preschool on Warren St. in Roxbury at 11 a.m. District 5 Councillor Rob Consalvo swings by Mike’s City Diner in the South End at 6:30 a.m. and then heads to a meet-and-greet at the 9th Street Apartments in South Boston at 11 a.m. District 8 Councillor Michael Ross visits Hebrew Senior Life at 1200 Centre St. at 10 a.m.

TWENTY YEARS AGO TODAY: The Sept. 9, 1993 Globe headline said, “8 who would be mayor jab in debate.” Brian McGrory byline on the story:

Suffolk County Sheriff Robert C. Rufo last night derided Acting Mayor Thomas M. Menino for committing a "rookie mistake" and "dropping the ball" on the teachers' union contract negotiations, marking a rare moment of discord in the first televised debate of the mayoral campaign.

All eight mayoral candidates strongly condemned the proposed teachers' pact, which goes to a vote before the School Committee Saturday, saying the pending agreement would cost Boston residents far too much money and offer too few meaningful reforms. "It is a $100 million insult," said candidate Christopher Lydon. "I wouldn't touch it with a stick."

But it was Menino, who in July said he planned to push for a contract resolution and then watched as the strategy backfired in September, who took the most heat on a hot-button issue, both from Rufo and later from Rep. James T. Brett.

WARD 16 DEMS ENDORSE WALSH: On Saturday, Ward 16 Democrats voted to endorse state Rep. Marty Walsh for mayor. The ward committee, chaired by Dan Hunt, had agreed to endorse up to two candidates, but only Walsh garnered enough votes to make the two-thirds threshold. Thirteen votes were needed for the threshold. On a second ballot, after the Walsh endorsement, Consalvo received 7 votes, DA Dan Conley received one vote, Councillor At-Large John Connolly received 3 votes. The committee also voted to back City Councillors At-Large Ayanna Pressley and Stephen Murphy, as well as candidates Catherine O’Neill and Annissa Essaibi-George. The committee’s membership includes City Clerk Maureen Feeney, former Ray Flynn aide Frank Doyle, and Dan Cullinane, who is running for state representative in the 12th Suffolk. They were allowed to endorse up to eight at-large candidates, but just the four made the threshold.

GOLAR RICHIE ON MNSBC: Former state Rep. Charlotte Golar Richie, who has struggled to meet fundraising goals, appeared on national television on Sunday to press her case, noting her time on Beacon Hill and as Mayor Menino’s housing chief. Golar Richie told MSNBC’s Melissa Harris-Perry that she has “no problem” with the number of the candidates in the race (12) and the number of candidates of color (six). The interview is available here.

FROM THE WEEKEND: In case you missed them, the round-ups for Saturday and Sunday. On Friday, we had an analysis of the endorsement that was roiling Dorchester last week.
