Do you plan to vote in the November 3 midterm election?
Massachusetts voters will decide 10 congressional races on November 3, 2026, including nine U.S. House seats and one U.S. Senate seat. The results could affect the balance of power in Congress.
Why it matters
Republicans hold a slim 218-seat House majority and a 53-45 Senate advantage, with two independent senators caucusing with Democrats. Outcomes in Massachusetts could shift the partisan balance in Washington.
The nonpartisan Cook Political Report rates all 10 Massachusetts races as solid Democrat, and Democrats currently hold all nine state House seats plus the Senate seat held by Sen. Edward J. Markey. The source does not say how these races could change the national majority.

Political Context
The Cook Political Report rates all 10 Massachusetts races as solid Democrat, meaning the state's contests are not expected to be competitive. Any national shift in congressional control would come from races outside Massachusetts.
Massachusetts voters' choices on November 3 will determine who represents the state in the House and Senate for the next term. Because the races are rated solid Democrat, the results are not expected to change the state's current delegation.
The takeaway
Massachusetts's congressional races are expected to remain Democratic, so the most consequential outcomes may come from competitive races elsewhere in the country. Readers can track how the broader House and Senate map develops as results come in.
What happens next
The Massachusetts congressional races will be decided on November 3, 2026, when voters cast their ballots in the midterm election.
