Client service is a core value at Mack-Sumner. That means we respect our clients, protect our clients and work as hard as we possibly can to help our clients succeed. When you need us, we’re there to get the job done.

We specialize in candidate campaigns, independent expenditures, member communication, issue advocacy and non-profit marketing. 

National and Congressional Candidates

Our team played a major role in electing President Obama and Democrats in just about every battleground U.S. Senate, Gubernatorial, and U.S. House race over the last decade. Sometimes that means we work directly for the candidate. Other times it means independent expenditures and member communication. Members of our team served as the lead mail consultants for President Obama in two battleground states and continues to serve as the lead mail consultant for progressive organizations every cycle.   

State Candidates and State Parties

Our partners have led the way on state legislative and state party/caucus work across the country. Our state work includes CA, OH, VA, PA, IL, WI, GA, FL, NC, SC and MS.

Local Candidates

We continue to work with a diverse group of local candidates across the country, including mayors, city councilmembers, sheriffs and countywide officers.
