Republican attorney and U.S. Marine veteran John Deaton has formally launched a campaign for the U.S. Senate seat currently held by Democratic Senator Ed Markey, entering the race with a message centered on affordability and a call for what he described as more active leadership from Massachusetts’ congressional delegation.
Deaton, who previously ran against Senator Elizabeth Warren (D-MA) in 2024 and garnered roughly 40 percent of the vote, said his experience in that contest reinforced his belief that a sizable share of Massachusetts voters is open to sending a new kind of voice to Washington. He pointed to economic strain on working and middle-class families as a driving factor in his decision to run again, framing the Senate campaign as a continuation of his prior effort.
Markey, who has served in Congress for decades and has held his Senate seat since 2013, has not actively engaged in the early stages of the race and has not made a public statement regarding his intentions for 2026. His absence from the political conversation in the commonwealth has drawn attention from observers, with some characterizing him as notably quiet as candidates begin positioning themselves. This lack of visible activity from Markey has led to uncertainty about whether he plans to seek another term.
Deaton emphasized his background as both a Marine veteran and an attorney who has represented individuals dealing with serious health conditions. He said those experiences shaped his perspective on the challenges faced by families and reinforced concerns about what he described as entrenched political interests within the state’s leadership. His announcement underscored a message aimed at voters who feel disconnected from longtime officeholders.
“Ed Markey is MIA, rarely seen here, and rarely delivering results in Washington, a place he’s called home since the 70s,” Deaton says. “Massachusetts can do better.”
The Senate race unfolds in a state long considered a Democratic stronghold, where incumbents often enter campaigns with significant advantages. However, Deaton’s performance in the previous statewide race has encouraged his supporters, who see an opportunity to tap into voter frustrations about affordability, economic pressures, and the broader direction of national politics.
With his announcement, Deaton becomes one of the first major candidates to formally step into the contest. Markey’s plans remain unclear, and the early phase of the campaign will likely focus on whether the senator re-enters the public conversation or maintains his current low profile as the political calendar moves closer to the 2026 election.
