Public Affairs

Building Coalitions. Mobilizing Communities. Earning Victories.

Winning on important issues takes more than a compelling argument. It requires the right strategy, the right messengers, and the ability to mobilize support where it matters most.

Liberty Square Group helps organizations shape public opinion, build powerful coalitions, and advance policy and political objectives. Our public affairs team brings decades of experience managing issue advocacy campaigns, ballot initiatives, and political campaigns at the local, state, and federal levels.

We combine campaign-tested strategies with research, message development, coalition building, and grassroots mobilization to influence decision-makers and drive results.

From organizing diverse stakeholders around a shared goal to executing statewide ballot campaigns, we understand how to build momentum, navigate opposition, and turn public support into meaningful action.

Our integrated approach connects political strategy, communications, and government relations, giving clients the expertise and resources to compete and succeed in complex public policy environments.

Ed Markey for Senate

As general consultant, developed and executed communications and outreach campaigns that elevated Sen. Ed Markey's progressive leadership, broadened his appeal, and mobilized Massachusetts voters around key policy priorities, helping secure a come-from-behind 2020 reelection victory after trailing by double digits in the polls. Provided similar assistance as Sen. Markey won resounding primary and general re-election victories in 2026.

Stephen Lynch for Congress

Dan Koh for Congress

Coordinated support from organized labor at district, state, and federal levels, including fundraising, endorsements, and field organization. Served as liaison between campaign and unions, nearly four dozen of whom endorsed Koh’s successful 2026 campaign.

Seth Moulton for Congress

Played a key role in Moulton’s historic 2014 congressional victory, helping a first-time candidate unseat a nine-term Democratic incumbent, beating out a 54-point deficit in early polling.

Statewide Ballot Campaigns

Collaborating with a diverse array of specialists and partners, LSG has worked on numerous ballot initiatives in recent years. Developed and executed a targeted communications strategy that elevated law enforcement support for Yes on 4 for Safer Roads, countered opposition messaging, and helped secure a statewide ballot victory in 2022 to protect the Work and Family Mobility Act, allowing Massachusetts residents to obtain driver's licenses regardless of immigration status. Teamed with union-backed Massachusetts is Not for Sale to combat 2024 ballot initiative put forth by rideshare and tech companies seeking exemptions from labor and wage laws. Developed messaging, built out coalitions, and provided hearing prep and legislative insight before dispute was resolved prior to question reaching ballot.

Municipal Ballot Campaigns

Provide strategic counsel and campaign support for local ballot initiatives, including school funding measures and debt exclusion campaigns in Belmont, Westwood, the South Shore, Martha’s Vineyard, and other Massachusetts communities.

Candidate Campaigns

Assist in electing numerous candidates to federal, state, and local office, including Middlesex District Attorney Marian Ryan, former Lieutenant Governor Timothy P. Murray, State Sen. Will Brownsberger, State Rep. Andy Vargas, State Rep. Simon Cataldo, State Rep. Adrianne Ramos, State Rep. Brandy Fluker-Reid, State Rep. Steve Owens, State Rep. Paul Mark, and State Rep. John Drinkwater.

Massachusetts House Victory Fund

Provide strategic political consulting and campaign support to Massachusetts Speaker of the House Ronald Mariano’s outside political operation, helping advance electoral priorities and support Democratic candidates for the Massachusetts House of Representatives. Since LSG took its role with the Fund, the Democratic caucus and supermajority have grown every election cycle.

The Blue Lab

Founded a political incubator that has supported dozens of Democratic candidates running for local and state office, many for the first time, while training more than 500 students from over 60 colleges and universities in political campaigns, grassroots organizing, and civic engagement, with a focus on lowering barriers for first-time candidates, women, and minorities.

Dana-Farber Cancer Institute

Built coalitions among labor unions to mobilize turnout at public hearings in support of DFCI’s new building initiative. By generating on the ground support, LSG ensured that DFCI was well represented by Boston’s key labor figures every step of the way, leading to the successful approval of a $1.7 billion hospital construction project that will revolutionize the Boston medical scene even further.
