Did Ed Markey Win? Yes — Senator Secures Massachusetts Democratic Primary Victory

Massachusetts voters delivered their verdict on Tuesday, September 1, 2026, and the answer to “did Ed Markey win” is a resounding yes. Longtime U.S. Senator Ed Markey defeated his highest-profile challenger yet, Rep. Seth Moulton, in the Massachusetts Democratic Senate primary, setting up a general election showdown this November against Republican John Deaton.

Ed Markey Wins Democratic Primary Over Seth Moulton

Multiple major outlets, including NBC News, CNN, and the Associated Press, projected Markey’s victory shortly after polls closed on primary night. Early returns showed Markey with a commanding lead over Moulton, and unofficial results indicated the incumbent senator captured roughly 70 percent of the Democratic primary vote to Moulton’s 30 percent — a decisive margin that surprised few political observers given Markey’s consistent polling lead throughout the campaign.

This marks Markey’s second consecutive primary victory against a younger challenger from the state’s congressional delegation. Six years earlier, in 2020, he turned back a challenge from then-39-year-old Joe Kennedy III.

Why the Race Drew National Attention

The primary became one of the most closely watched Senate contests of the 2026 midterm cycle for several reasons:

• Age was central to the campaign. Markey, who turned 80 shortly before the primary, faced repeated criticism from Moulton over whether it was time for generational change in Democratic leadership.
• Moulton framed the race around renewal. The 47-year-old congressman argued that Democrats needed younger leaders following the party’s 2024 presidential election loss, and he pointed to concerns that had also surrounded former President Joe Biden’s age.
• Markey leaned on progressive credentials. He campaigned heavily on his record as co-author of the Green New Deal and secured endorsements from prominent progressives including Senators Bernie Sanders and Elizabeth Warren, along with Rep. Alexandria Ocasio-Cortez.
• Transgender rights became a flashpoint. During debates, Markey criticized Moulton over past comments regarding transgender athletes, an exchange that drew significant media coverage in the campaign’s final weeks.

Spending and Endorsements

Despite being outspent on advertising — Moulton and his allies spent roughly $7.1 million compared to about $3.9 million from Markey and his supporters — Markey’s deep name recognition, decades of incumbency, and broad institutional support from Massachusetts Democrats proved decisive. Attorney General Andrea Campbell and a majority of the state’s Democratic congressional delegation also backed Markey ahead of the vote.

What Happens Next: The November General Election

With the primary settled, Markey now advances to face Republican John Deaton, a cryptocurrency attorney who ran unopposed on the GOP side of the ballot, in the November 3, 2026 general election. Massachusetts has not elected a Republican to the U.S. Senate since 2010, making Markey the strong favorite heading into the fall.

Following the results, Moulton publicly congratulated Markey and pledged his support, telling supporters that Democrats “must stand united this November to protect our democracy and defeat Donald Trump.”
