In 2001, the Boston Democratic Socialists of America Exec Board recommended that members vote to endorse incumbent Alderman-at-large Denise Provost in Somerville, and Felix Arroyo for an at-large City Council seat in Boston.
On August 18 2001, Boston Democratic Socialists of America Summer conference voted to endorse Denise Provost and Kevin Tarpley for re-election to Somervilles Board of Aldermen and Felix Arroyo for an At- Large seat on the Boston City Council.
Long-time progressive activist Felix Arroyo was raised in Puerto Rican public housing; his father was a police detective, his garment seamstress mother an ILGWU member.
Past President of the Boston School Committee and current critic of the MCAS test, Felix Arroyo was a policy advisor to both Mayor Ray Flynn and Senator John Kerry, and an active opponent of U.S. Central American policy in the 1980s. He is endorsed by the SEIU State Council, Boston NOW, CPPAX, Mel King, Boston City Councilor and DSA member Chuck Turner and State Rep. Shirley Owens-Hicks.
Despite strong support from segments of the black and Latino community, Arroyo finished 5th in his quest for one of the 4 At Large seats on the City Council.
2005 DSA endorsement
The September 2005, members meeting of Boston Democratic Socialists of America voted to endorse two candidates for re-election this November 8: Boston City Councilor At Large Felix Arroyo and Somerville Alderman At Large Denise Provost. "Both have been consistent and creative advocates for social and economic justice."
Brought up in a trade union (ILGWU) household in Puerto Rican public housing, Felix Arroyo is the first Latino elected to the Boston City Council. He has been a strong supporter of countless progressive causes, from removing lead from Boston’s drinking water, to reforming the unfair CORI system which keeps ex-felons from securing employment, to picketing with striking N Star workers. He also has thoughtful proposals for alleviating Boston’s affordable housing crisis, and to make city planning inclusive and transparent instead of a plaything for developers. His backers range from Senator John Kerry, Barney Frank, and the Stonewall Democrats of Massachusetts to ACORN and the Boston Carmen’s Union local 589.
DSAers in Boston and Somerville received a mailing endorsing both these candidates in early October, and have been participating in their campaigns. 
DSA "on the ground" support
- We (Boston Democratic Socialists of America) continued our electoral work with the Massachusetts Alliance (formerly the Commonwealth Coalition), a grouping of unions, civil rights groups and other progressive forces who strive to provide effective support in a targeted number of state legislative races. Through the Alliance we strengthened our relationship with key allies and, by door-knocking, phone-banking and mailings, helped elect Linda Dorcena Forry, Chris Speranzo and Pat Jehlen to the State House. Boston DSA also supported (on our own) the successful City Council re-election races of Felix Arroyo in Boston and Denise Provost in Somerville.
- Our plans for 2006 include projects voted as priorities by DSA’s recent National Convention, especially focusing on the low-wage economy (i.e., Wal-Mart, healthcare). And we’ll maintain our involvement with the Alliance—currently we’re working on the State Rep. races of Claire Naughton in Foxboro and (again on our own) Denise Provost in Somerville.
Bernie Sanders fundraiser
On June 13 2006, almost 50 supporters attended a fundraiser at the Somerville Massachusetts home of Dick Bauer and Roberta Bauer to help Congressman Bernie Sanders in his quest to become the next U.S. Senator from Vermont. The reception, organized by local volunteers as part of a national project of the Democratic Socialists of America Political Action Committee, raised almost $5,700 for the Sanders Campaign. Sponsors of the event included Boston City Councilor Felix Arroyo, State Senator Patricia Jehlen, and State Representatives Anne Paulsen, Carl Sciortino, Alice Wolf and Denise Provost. Denise Provost was also one of the featured speakers, along with DSA member Rand Wilson of IUE-CWA 201, and Bernie sanders' son Levi Sanders. 
DSA Forum on globalization
On May 30 2007, at the Democracy Center in Cambridge, Boston Democratic Socialists of America sponsored a discussion on immigration and globalization with IUE-CWA 201 President Jeff Crosby and Boston City Councilor Felix Arroyo. David Knuttunen of DSA began by analyzing the rise of “involuntary” immigration resulting from corporate globalization, including U.S. trade and development policies. This point was developed further by Councilor Arroyo, who sketched in some of the history of U.S. intervention in Latin America, and President Crosby, who related some of his organizing experiences. 
2007 Debs-Thomas-Bernstein Awards
On September 27, 2007, Boston Democratic Socialists of America presented its annual Debs-Thomas-Bernstein Award to a couple Marie Kennedy and Chris Tilly, "two long-time champions of economic justice and grassroots democracy".
The awards reception took place at the Jamaica Plain home of Marcia Peters and David Karaus. Honorary Co-Chairs for this event were Boston City Councilor Felix Arroyo and Elaine Bernard, Director of the Harvard Law School Labor and Worklife Program.
