Democratic



The 2026 United States Senate election in Massachusetts will be held on November 3, 2026, to elect a member of the United States Senate to represent the Commonwealth of Massachusetts. Primary elections will be held on September 1, 2026. Incumbent two-term Democratic Senator Ed Markey, who was re-elected in 2020 with 66.2% of the vote, is running for a third full term.

Markey, who will be 80 years old at the time of the 2026 election, has faced calls to retire due to his age.[1] His main primary challenger, U.S. Representative Seth Moulton, has criticized Markey's choice to run for re-election rather than retire throughout the campaign.[2] Moulton has also expressed support for a constitutional amendment creating an age limit for members of Congress.[3]
