Maine’s Senate primary spotlights Democrats’ generational rifts
On a chilly night in early April, a couple dozen people crowded into a high school classroom to hear Democratic Gov. Janet Mills make her case for the U.S. Senate. The room had that late-night classroom smell—chalky and a little stale—and the fluorescent lights made everyone look a touch more tired than they probably felt.
Evelyn Spencer, a paralegal from Sabattus, stepped forward to praise Mills as “incredible,” then left with a different plan forming. She said she’s decided to vote for oysterman and combat veteran Graham Platner, calling for a Democrat who’s “focused on building power over time,” and warning Mills’s one-term pledge could be a problem in a deadlocked Senate where a freshman might struggle. Spencer wasn’t alone in sounding a bit restless, even while saying she liked the governor.
By normal predictors, Mills should be the heavy favorite in the Democratic Senate primary on June 9. She’s a two-term governor with a long résumé and, after decades in public service, the kind of credibility voters say comes from being vetted. Platner, by contrast, is newer to politics, and his past has included scandals that many residents describe as questions about his character. Still, Misryoum newsroom reporting shows he’s leading in polls by an average of 25 points, drawing grassroots enthusiasm across the state—and roughly 15,000 volunteers—and even out-fundraising Mills despite the governor’s support from Senate Minority Leader Chuck Schumer and the Democratic Party’s Senate campaign arm.
That mismatch between “liking” and “leaning” is basically what’s driving the generational tension inside Maine’s Democratic coalition. Some voters want their party to fight back harder against President Donald Trump. Others say they’re looking for a fresher economic vision. And a chunk of the electorate, frankly, just wants a newer generation of leaders. Misryoum analysis indicates that with relatively little daylight between Mills and Platner on issues, the nomination fight is increasingly about experience and style—who feels ready, who feels dangerous to bet on, and who feels like a match for the political moment people think Washington is failing them.
At a town hall in Millinocket—population about 4,000—Platner spent the evening talking to more than 120 people in a husky, conversational tone that draws crowds even in sparsely populated corners of Maine. He comes off comfortable and casual, but the message has teeth: a system he describes as rigged, run by an “oligarchy” that conspires against working people. In his view, both major parties at the national level are too entangled with corporate power. He tells supporters they can go after wealth stolen from working-class Americans over the last 50 years and redirect it toward social programs like education and universal child care. Endorsements from Sens. Elizabeth Warren of Massachusetts and Bernie Sanders of Vermont have helped underline his “progressive” branding—even if he pushes back, arguing his stance is actually moderate.
Mills, for her part, entered the race in October and has leaned on familiarity—deep personal connections around the state and a steadier rhythm of smaller events, often house parties and dinners. At an event in Auburn, she greeted voters by name and told them it was time to change who sits in Congress if the Senate and Congress weren’t standing up to Trump. She said she doesn’t need the job, but wants to “save my country,” and warned that if Democrats don’t act soon, the country could be in trouble. Her record—Medicaid expansion, free community college tuition, and universal free school lunches—is central to her pitch, along with her argument that she’s already proved she can win statewide twice and stand up to Trump, even taking a famous swing at him after he threatened funding over transgender athletes.
Yet the generational critique doesn’t really go away. Mills would be 79 when sworn in to the Senate, and some progressives worry about her pledge to serve only one term—especially with Angus King, the independent senator who caucuses with Democrats, potentially facing reelection in 2030 at age 82. Some of the governor’s progressive approval has dipped, with frustration tied to her opposition to a voter-supported red-flag law on guns, labor-related bills, and her veto of a measure expanding sovereignty for the Wabanaki Nations. Meanwhile, Platner’s character questions have continued even as he apologized for deleted Reddit posts from 2013 and 2021 and pointed to post-traumatic stress disorder after tours. He also apologized for and covered up a tattoo resembling the Totenkopf after learning it’s associated with Nazis, saying he got it while on leave in Croatia in 2007.
Even with all of that, Misryoum newsroom reporting suggests Democrats aren’t losing sleep about turnout. This year’s caucuses to elect Democrats to the state convention saw nearly 20% higher turnout than in 2024, according to Marcia Myers, chair of the Hancock County Democratic Committee. “People are not apathetic,” she said. “People are really ramped up.” Whether that energy ultimately produces a Mills victory or a Platner surge, the party’s internal fight looks less like a policy debate and more like a generational reckoning—one that might be carrying its way all the way into the general election against five-term GOP Sen. Susan Collins.
