Does control of the U.S. House by one party better represent your national interests?

Massachusetts voters will cast ballots for all nine U.S. House seats on November 3, 2026. The election features six contested districts across the state.

Why it matters

The outcome of these races contributes to the national effort by Democrats to regain control of the U.S. House of Representatives. To achieve this majority, the party must net four additional seats currently held by Republicans.

All nine current members of the Massachusetts U.S. House delegation are Democrats. The election requires a net gain of four seats held by Republicans nationwide for Democrats to secure a majority in the 435-seat chamber.

The players

Seth Moulton

He is a politician who served in the U.S. House of Representatives and sought the Democratic nomination for U.S. Senate in 2026.

Katherine Clark

She is a member of the Massachusetts congressional delegation who is projected to potentially serve as House majority leader if Democrats win control.

The details

The 6th Congressional District seat is currently open following the retirement of Seth Moulton. Moulton previously opted to pursue the Democratic nomination for U.S. Senate in the same election cycle.

November 3, 2026, is the date for the U.S. House elections in Massachusetts.

Political Context

These contests follow the biennial cycle mandated by the U.S. Constitution's Article I, Section 2 requirement for biennial House elections. The elections reflect the ongoing national struggle between parties to secure a majority in the chamber.

Massachusetts voters will determine the legislative representation that impacts future federal policy and potential leadership positions for the state's delegation. The results will directly influence whether the Democratic Party can successfully secure the four additional seats required for House control.

The takeaway

Voters should review the list of candidates for their specific district to understand the platforms of both incumbents and their opponents. Monitoring the 6th Congressional District is particularly important as the seat is open and guaranteed to have a new representative.
