Markey Projected to Win Massachusetts Senate Race

Live Poll

Do you think long-serving members of Congress should keep seeking reelection?

Sen. Ed Markey is projected to win reelection to the U.S. Senate from Massachusetts, defeating Republican John Deaton. The projection was made by Decision Desk HQ.

Why it matters

Massachusetts has not elected a Republican senator since 2010, and earlier polls showed Markey well ahead of Deaton. A win would give Markey a third Senate term in Massachusetts.

Markey has served 13 years in the U.S. Senate and 50 years in Congress overall, and a reelection win would make this his third Senate term. Final vote totals and the margin of victory were not provided in the source extraction.

The players

Ed Markey

Ed Markey is a Democratic U.S. senator from Massachusetts who has served in Congress for 50 years and is 80 years old.

John Deaton

John Deaton is a Republican attorney and Marine Corps veteran who challenged Markey in the general election.

Decision Desk HQ

Decision Desk HQ is a U.S. election-results and race-projection service that made the call in this race.

The details

Markey defeated Democratic challenger Rep. Seth Moulton in the primary, which he said was made possible by young progressives, and defeated Republican attorney and Marine Corps veteran John Deaton in the general election. Markey said this would be his last time running for office.

- 2010: Massachusetts last elected a Republican senator.
- November 4, 2026: General election in which Markey was projected to win.

Political Context

Massachusetts has not sent a Republican to the U.S. Senate since 2010, the last such election in the state. The Markey projection continues that Democratic streak, extending a pattern that the state's voters have maintained in recent Senate contests.

Markey's projected win means Massachusetts residents will keep the same Democratic senator for another term. The result leaves the state's Senate delegation unchanged, with no Republican senator in office.

The takeaway

A projected result is not a certified outcome, so readers should watch for final vote totals and official certification in Massachusetts before treating the race as settled.
