Republican attorney and Marine veteran John Deaton of Bolton won the Massachusetts Senate primary on Tuesday and will now face longtime Democratic Senator Elizabeth Warren in November.

Deaton, a personal injury attorney and crypto advocate, moved to Massachusetts from Rhode Island last year. In the primary, he ran against Ian Cain of Quincy, Massachusetts’ first black and openly gay city council member, and Bob Antonellis, an engineer and political newcomer from Medford.

Deaton, 56, has not yet said whether he will vote for Donald Trump in the presidential election; Antonellis was the only candidate to pledge his support to the leading candidate in this traditionally conservative state.

Deaton was far better funded than his competitors, thanks in large part to a $1 million loan he made to his campaign. He more than doubled Cain’s spending and had $975,000 on hand at the end of June, according to FEC records. At the same time, Cain still had about $22,000 in his war chest.

Deaton has often told the story of his childhood in Detroit’s poor and violent Highland Park neighborhood. He said he witnessed a thief stab his mother to death and had a gun shoved into his mouth on his first day of high school.

He said he broke the cycle of poverty by working his way through college and law school before joining the Marine Corps and fighting cartels for seven years in the 1990s as a special assistant to the U.S. attorney in Yuma, Arizona.

Deaton said he has spent the last 22 years representing injured workers in litigation against “corporations and insurance companies.”

Massachusetts has not elected a Republican to statewide office since moderate Republican Gov. Charlie Baker left the governor’s office in January 2023. Polls suggest Warren, herself a former Republican, is likely to retain her seat in November.

The state Republican Party has fielded only challengers to Warren and two other incumbents: Democratic Reps. Stephen Lynch and Bill Keating. Seven other Democrats in the Massachusetts House of Representatives, none of whom ran in the primary, are expected to win outright in the general election.

Warren faced a tough campaign when she defeated Republican incumbent Scott Brown in 2012. She received more than 60% of the vote in 2018, and President Biden won the state with 66% of the vote in 2020.

Deaton has focused on the refugee crisis and Warren’s “removal” from office.

“Thanks to the failed policies and partisanship of career politicians like Elizabeth Warren, every state is now a border state, and Massachusetts must face the consequences,” Deaton said in a campaign video.

Florida Governor Ron DeSantis flew migrants to the wealthy enclave of Martha’s Vineyard in Massachusetts in 2022.

Deaton wrote on X on Monday that Warren is “more focused on her national profile and special interest groups” than on spending time in local communities. “This will cost her dearly on November 5th.”

All three candidates have made the border the focus of their election campaigns and have sharply criticized the state’s protection policy.

Antonellis said he would work to end Massachusetts’ sanctuary state status, which he said was “destroying entire regions of the country.” He had also pushed for a ban on offshore and onshore wind farms and had come under fire for claiming the Sept. 11 terrorist attacks were an inside job.

“Washington is taking away our freedoms, systematically, even diabolically,” Antonellis wrote on his campaign website. “9/11 was an ‘inside job,’ we’ll talk more about Harvard’s role in that. It was done in part to get American patriots to support the Patriot Act, which forces Americans to nearly strip naked just to board a plane and which legalizes surveillance of everyone.”
