Two U.S. Senate contenders, Republican John Deaton and Democratic Rep. Seth Moulton, said Monday they will meet on a debate stage ahead of Massachusetts’s primary, while incumbent Sen. Ed Markey has not yet confirmed whether he will take part. Deaton framed his challenge as a call for accountability and proposed a schedule of multiple three-way debates through the primary, plus additional matchups with the eventual Democratic nominee. Moulton welcomed the chance to let voters compare what he called "different visions for the future of our country." The exchange adds fuel to a race already drawing national attention and puts more pressure on Markey to decide whether he will show up.
As reported by the Boston Herald, Deaton posted a May 4 press release and social media post pressing Markey and Moulton to appear, and said he would debate even if the senator refused to join. Moulton, linking a state Democratic Party call for debates, responded that "the people deserve to hear from us." The Herald also noted that Markey's campaign did not respond to inquiries about whether he would participate.
Deaton's Challenge And His Case
Deaton, a Marine veteran and trial lawyer who ran statewide in 2024, published a formal May 4 press release laying out his debate plan and urging both Democrats and Republicans to "lead by example." The release appears on John Deaton for Senate, and GBH has profiled him as a personal-injury attorney and crypto advocate whose outsider messaging is central to his pitch to voters.
Where The Primary Stands
Rep. Moulton, who has represented Massachusetts’s 6th District in the U.S. House since 2015, said he welcomed the chance to put his record next to other candidates and has been stepping up in-person events as he builds a statewide case. His office details his committee work and recent news on Moulton's House website. Polling suggests Markey still holds an advantage in the Democratic primary: a Suffolk University/Boston Globe survey put the incumbent roughly in the mid-40s and Moulton near 30 percent, a topline reported by NBC Boston.
What To Expect Next
The practical questions now move to center stage: who will host and moderate these debates, what issues will make the cut, and whether party leaders will nudge the senator to participate. Per the Boston Herald, Markey's campaign did not answer requests about appearing Monday, and Deaton’s team says it will move forward with scheduling unless the senator signs on through John Deaton for Senate. Debate logistics are likely to serve as an early test of momentum as the race heads toward the Sept. 1 primary.
