Nobody in the South End seems to know who’s behind the new Mass and Cass Political Action Committee (PAC) that came out of the blue last week.

The PAC filed with the state last week.

Its goal is to “inform voters of and advocate for additional political action around the public health and public safety crisis at Mass and Cass.” It also distributed a survey to elected leaders to ask their stances on aspects of the addiction crisis at the Mass and Cass intersection, from increasing police patrols to involuntary commitment of drug users.

The PAC, also known as Residents for a Safe & Healthy South End and Lower Roxbury, claims to be run by local residents who are tired of the lack of effective action around the crisis. But as of Monday, multiple politically active South End residents and civic leaders said they did not know anyone involved with the new committee.

Brian McCarter, a South End resident who is actively involved in neighborhood civic organizations and frequently files Mass and Cass related public records requests with the city, said he had “no idea” who was behind the new PAC.

“Normally I’m the first call when this goes down,” McCarter said. “No clue. Everyone I’ve asked doesn’t know.”

McCarter noted that the Boston Herald, which first reported on the formation of the group two weeks ago, had named the Chick Montana Group, a popular campaign finance consulting company among Massachusetts electeds, as the group’s finance manager.

The PAC’s filings list Gemma Martin, principal of the Chick Montana Group, as the group’s treasurer. The filings do not list any other names.

When asked directly, an unnamed spokesperson for the PAC would not answer who or even how many people were involved in the group. “The mission of the PAC is not to focus on those organizing, but rather highlighting the positions of elected officials and candidates,” they said in an email. “We think that their positions on these issues should be everyone's focus.”

Tiane Donahue, of South End nonprofit performing arts school Boston City Lights, also had no information about the people behind the PAC.

“I do know the South End Business Alliance had a community forum a couple of months ago, with a request for no press [and] no politicians, and the Mass and Cass challenges were definitely a significant part of the discussion, with some emotional sharing of concerns,” Donahue said.

When asked about the PAC, one member of SEBA directed The Boston Guardian to contact McCarter.

Mass and Cass leaders who don’t live in the South End haven’t had any more luck in identifying the PAC organizers.

Rishi Shukla, who is the head of a Downtown neighborhood association but serves on two Mass and Cass task forces in the South End, said he had only heard “rumblings” about the PAC “over the past few weeks”; Josh Kraft, who pledged to give $3 million to organizations addressing Mass and Cass, said he didn’t know anything about the PAC beyond what had already been reported by the Herald.

The group’s spokesperson said the PAC had come “in response to years of conversations about the worsening public health and public safety crisis at Mass and Cass.” It will be funded entirely through grassroots donations from community members.
