On June 9, 2026, Maine’s political landscape was jolted by the results of its primary elections, setting the stage for what is shaping up to be one of the most closely watched Senate races in the country this November. At the center of the storm is Graham Platner, a progressive oyster farmer whose insurgent campaign has not only weathered a barrage of scandals but also ended the political career of incumbent Governor Janet Mills. Platner will now face off against Republican Senator Susan Collins, a five-term incumbent, in a contest that could determine control of the U.S. Senate.
According to live results reported by CNN and detailed town-by-town breakdowns from The Portland Press Herald, Platner clinched the Democratic nomination with a commanding 77.7% of the vote. Governor Mills, who had suspended her campaign in April due to lackluster fundraising and waning enthusiasm, still managed 16.7% after remaining on the ballot. Former government official and 2024 Senate nominee David Costello trailed with 5.6% of the vote. The Associated Press and Decision Desk HQ called the race for Platner at 9:07 p.m., cementing his status as the Democratic standard-bearer in a high-stakes general election.
Platner’s path to victory was anything but straightforward. As reported by the Bangor Daily News and The Washington Post, his campaign has been dogged by controversies, including revelations that he sent sexually explicit messages to several women early in his marriage, accusations of toxic behavior by ex-girlfriends, and criticism over a Nazi-linked tattoo he has since covered. Old offensive social media posts targeting women, Black people, and rural Mainers also surfaced. Platner has publicly apologized for his Reddit posts and denied any inference that he has been violent in past relationships. In a campaign framed around personal growth and a working-class movement, Platner told supporters, “This is because of you,” crediting his staff and volunteers for his primary win and promising to earn the trust of those who did not vote for him.
Despite the controversies, Platner’s grassroots support held firm. He led in polls for months, and his campaign’s early fundraising surge forced Mills to bow out, though she remained on the ballot. Platner’s victory speech emphasized unity and gratitude: “It’s my job to earn the trust of those who did not vote for me,” he said, striking a conciliatory tone amid the heated rhetoric that has marked this race.
But the path ahead is fraught with challenges. As noted by WGME and The Washington Post, ranked choice voting played a pivotal role in the Democratic primary, especially in the 2nd District and the gubernatorial contest, reflecting Maine’s ongoing experiment with alternative voting systems. Platner’s campaign, while successful in the primary, now faces skepticism from cautious Democrats, independents, and a deluge of advertising from Collins-aligned groups. According to AdImpact data cited by the Bangor Daily News, more than $150 million in advertising time has already been reserved for the race—$100 million of it from Republicans. This figure surpasses the $120 million spent during Collins’ record-smashing 2020 campaign.
Republican groups wasted no time launching attacks. On primary night, a pro-Collins organization released two ads featuring Mainers reading aloud Platner’s old offensive posts, aiming to sway undecided voters and highlight what they describe as character flaws. Collins’ campaign, through spokesperson Shawn Roderick, emphasized a focus on results over rhetoric: “Mainers aren’t looking for bitter campaigns, grand promises, or angry speeches riddled with lies,” Roderick said. “They’re looking for results. They want affordable health care, safe communities, good-paying jobs, strong schools, and someone who will show up and do the work.”
Platner has not shied away from firing back. At a rally in Bar Harbor, he accused Collins of evading scrutiny during her nearly three decades in the Senate and argued that his private life had been “weaponized” by opponents. Platner has cast Collins as emblematic of a corrupt system beholden to corporate donors, framing his campaign as a crusade for working-class Mainers. His platform includes support for Medicare for All, a billionaires tax, immigration reform, tribal sovereignty, and ending so-called forever wars—positions that have energized progressives but prompted unease among party centrists.
This unease is not limited to local Democrats. As reported by CNN, centrist U.S. Representative Josh Gottheimer of New Jersey publicly called for Platner to withdraw from the race, citing the controversies. Yet, leading progressives such as Senators Bernie Sanders of Vermont and Elizabeth Warren of Massachusetts have stood by Platner, underscoring deep divisions within the Democratic Party over the best path forward in a must-win race.
The stakes could hardly be higher. As The Washington Post observed, unseating Collins—a fixture in Maine politics and a key Republican moderate—remains crucial for Democrats hoping to flip the Senate. Collins is seeking her sixth term, and her reputation for bipartisanship has helped her weather past challenges. But Platner’s candidacy, with its blend of outsider energy and progressive policy, presents a new kind of threat, one that has already upended Maine’s political status quo.
Voters across the state, from Portland to Presque Isle, have been inundated with campaign messaging. The Portland Press Herald’s VoteHub project has broken down the results town by town, offering Mainers an unprecedented look at how their communities voted and what issues are driving the electorate. The Democratic and Republican primaries for governor and Senate have been mapped in detail, revealing regional divides and the growing importance of ranked choice voting in shaping outcomes.
For many Mainers, the scandals swirling around Platner are less important than his willingness to speak plainly. Bobby Taylor, a 58-year-old truck driver and independent who voted in the Democratic primary, told the Bangor Daily News, “I’m kind of a lot like Graham. I have a big mouth. I say the way things are, and I’m not scared of it. I don’t hide it. I think he’s very upfront.” This sentiment captures a broader frustration with politics-as-usual and a desire for authenticity, even if it comes with rough edges.
As the general election campaign kicks into high gear, Maine finds itself at the center of the national political conversation. With more than $150 million already committed to advertising, and both parties viewing the race as pivotal, the months ahead promise to be as contentious as they are consequential. Platner’s victory in the primary is a testament to the power of grassroots organizing and the shifting winds in American politics. Whether he can translate that momentum into a win against Collins—and whether Mainers will embrace his brand of unapologetic progressivism—remains to be seen. One thing is certain: the eyes of the nation will be on Maine this November.
