AUGUSTA – Graham Platner, a United States Army veteran and oyster farmer, won the Maine Democratic primary for the U.S. Senate on Tuesday, securing a general election matchup against incumbent Republican Senator Susan Collins.
The contest is viewed as a top priority for Democrats seeking to flip a Republican-held seat to claim control of the Senate in November. Collins, first elected in 1996, is currently the last Republican senator representing a New England state.
The race takes place against a backdrop of shifting political alignments in Maine, which backed Democrat Kamala Harris over Donald Trump in the 2024 presidential election.
Platform and Political Support
Platner, 41, has centered his campaign on economic issues and social services, specifically:
- The rising cost of living
- Housing affordability
- Healthcare access
He has argued that Maine’s working- and middle-class families are being squeezed by stagnant wages and high prices, and has called for expanded federal investments in affordable housing and rural healthcare infrastructure.
His candidacy has earned early endorsements from progressive figures, including Senator Bernie Sanders, positioning Platner on the left flank of the Democratic caucus he hopes to join. However, Governor Janet Mills, who withdrew from the race citing fundraising difficulties, has not yet endorsed Platner, underscoring ongoing tensions within the state party between its centrist and insurgent wings.
The winner of the Maine Senate race will help determine control of a chamber that confirms federal judges and Cabinet members and shapes national policy on issues ranging from healthcare and climate to military deployments under the framework of the U.S. Constitution’s allocation of powers to Congress.
Personal Conduct and Campaign Controversies
The victory follows a period of intense scrutiny regarding Platner’s past. His campaign has been clouded by reports of sexually explicit messages sent to women while he was married, as well as allegations of physical intimidation brought forward by a former girlfriend. The Platner campaign has disputed these claims and has accused political opponents of weaponizing his personal history.
Further scrutiny arose from old online posts in which Platner appeared to endorse political violence and made dismissive remarks regarding military sexual assault. Platner attributed these comments to a period of acute mental health struggles, including depression and PTSD following two combat deployments, and has said he is undergoing treatment.
Platner has also issued apologies for previous posts that contained homophobic slurs and insults directed at law enforcement and rural communities. Additionally, a tattoo later identified as a Nazi symbol prompted investigation; Platner maintained he was unaware of the symbol’s significance and has since had the tattoo covered. He has framed these episodes as evidence of personal growth but acknowledged that voters will have to decide whether they trust his assurances.
Contrasting Campaign Visions
In a victory speech delivered in Blue Hill, his birthplace, Platner framed his candidacy as a narrative of redemption and a challenge to what he describes as an entrenched political establishment in Washington.
“If you believe, as I do, that we can change our politics and change our country, then you must also believe that people can change,” Platner told supporters. “And the reason I believe that is because I have lived it.”
Platner, a veteran of both the Marine Corps and the Army who served in two conflicts, criticized Collins for her role in confirming conservative Supreme Court justices and her support for what he termed “endless wars.” He has argued that Collins’ votes helped shape a court that has rolled back abortion rights and other precedents, and has pledged to back federal protections for reproductive healthcare.
“You and your friends profited, and my friends died,” Platner said, addressing Collins. He has promised to push for tighter oversight of defense spending and to require clearer authorizations from Congress before extended overseas deployments, in line with debates over reforming the federal war-powers framework.
Collins, who ran unopposed in the Republican primary, has pointed to her seniority and her role as chair of the powerful Committee on Appropriations-which oversees the discretionary spending of the U.S. government-as primary reasons for her reelection. Her campaign has emphasized that her position allows her to steer federal funding to Maine at a time when partisan gridlock often stalls major legislation.
Shawn Roderick, a spokesperson for Collins, stated: “While others talk about revolution and division, Susan Collins is delivering for Maine communities by funding rural hospitals, supporting our shipbuilders and fishermen, improving infrastructure, expanding broadband, and strengthening public safety.”
Roderick added that Maine voters are “practical” and focused on whether their families are better off, casting Collins as a steady hand in an increasingly polarized Senate.

Other Maine Primary Outcomes
While the Senate Democratic nominee is settled, other races in the state remain undecided. Ranked-choice tabulations are required to determine the winners of the Democratic gubernatorial primary and the race for the 2nd Congressional District, as no candidates secured an outright majority in those contests.
Maine’s ranked-choice system, adopted for federal offices and certain statewide races, allows voters to list candidates in order of preference and redistributes votes from lower-performing contenders until one surpasses 50 percent, a process that can delay final results but is intended to ensure broader consensus.
The eventual Democratic nominee for the 2nd Congressional District will face former Governor Paul LePage, a close ally of Donald Trump, in a race that will test how far the state’s more rural and conservative districts are shifting in the post-Trump era.
