Voters in select parts of Dorchester, Roxbury and Mattapan will go to the polls on Tuesday, Sept. 8 in a city preliminary election that features only two district seats in contention. With only five candidates seeking one of the four at-large council seats, there will be no balloting in the rest of the city of Boston next Tuesday.

In District 4, the longest serving city councillor, Charles Yancey, is attempting to stave off two challengers: Andrea Campbell, a lawyer and former member of Gov. Deval Patrick’s administration, whose grassroots energy and resonant personal history has provided a financial windfall for the campaign; and Terrance Williams, a community activist who ran unsuccessfully against Yancey in 2013, stresses the importance of youth outreach. Jovan Lacet, who will also appear on the ballot in District 4, has withdrawn his candidacy and endorsed Yancey. Lacet says he will mount a write-in campaign for at-large.

Yancey’s opponents hope to overcome the incumbent’s 32 years in office and the notoriously low turnout of council-only election years. Yancey, for his part, has re-emphasized his commitment to the community and has promised to continue serving his constituents.

In District 7, incumbent Tito Jackson faces a slate of familiar names, squaring off against former State Rep. Althea Garrison, TOUCH 106.1 co-founder Charles Clemons, pro-life advocate Roy Owens, Kevin Dwire, and community activist Haywood Fennell Sr. All of Jackson’s opponents have run for the seat in the past and Jackson has promised to continue to push for transparency and accountability on the part of the city government.

Most of the preliminary candidates are scheduled to attend a candidates’ forum hosted by the Black Economic Justice Institute at the Dudley Branch Library on Sept. 3. The event will run from 5-7:30 p.m. and will feature discussion of black economic interests and a round-robin style discussion with candidates and attendees from Dorchester, Mattapan, and Roxbury, the Institute said in it announcement.

All District 4 candidates have confirmed their attendance, and the only candidate currently not confirmed from District 7 is Garrison.

In related news, the council pay raise discussion continues to shift, with Mayor Martin Walsh proposing a raise of 13.7 percent -- higher than the independent board’s recommendation of 11 percent -- to $99,500. Council president Bill Linehan filed last week for another raise, this time for a salary of $105,000.

Some sitting councillors and several challengers have been outspoken about their disapproval of the push for a higher wage, including Dorchester’s Ayanna Pressley and fellow at-large councillor Michelle Wu. After city councillor attendance records were made public in the Boston Globe last week, at-large challenger Annissa Essaibi-George vehemently criticized the salary discussion in light of poor attendance by some of the raises’ staunchest advocates.  

“Enough is enough,” Essaibi-George said in a statement. “Bostonians demand more from their elected officials, especially when it comes to improving our schools, making our streets safer, and creating economic opportunity in all of Boston’s neighborhoods.”

Polls will be open in districts 4 and 7 from 7 a.m. to 8 p.m. on Tuesday.
