Maine Gov. Janet Mills Inches Closer to Senate Run: Interviewing Campaign Staff Amid Democratic Push
Maine Democratic Gov. Janet Mills is ramping up her preparations for a potential 2026 U.S. Senate bid, quietly interviewing campaign managers and key staffers to challenge Republican Sen. Susan Collins. The term-limited governor’s moves signal a growing seriousness about jumping into the race, positioning her as Democrats’ top recruit in a state that former Vice President Kamala Harris carried in 2024.
The Staff Interviews: A Sign of Momentum
Mills, who has been term-limited since her 2022 reelection, is in the process of vetting potential campaign managers, according to multiple sources familiar with the discussions. The interviews, first reported by Punchbowl News and confirmed by Politico, indicate she’s building the infrastructure needed for a high-stakes Senate contest. While Mills hasn’t formally declared, these steps suggest she’s leaning toward a run, with a decision expected by November 2025.
A person close to Mills told reporters that the governor feels a sense of obligation to consider the bid, particularly after her public clashes with President Donald Trump over issues like transgender athletes’ rights earlier this year. “Every day I pick up the newspaper and I read the headlines… there are a lot of very disturbing things going on in Washington,” Mills said recently, sounding every bit like a candidate critiquing the GOP-led Senate.
Background: Mills’ Political Rise and Maine’s Senate Landscape
Janet Mills, 77, has been a fixture in Maine politics for decades, serving as attorney general before winning the governorship in 2018 with 50% of the vote and reelection in 2022 by 13 points. Known for her moderate, pragmatic style, she’s navigated a divided legislature to pass key legislation on healthcare, education, and climate resilience. Her approval rating hovers around 50%, making her a formidable figure in a state where independents play a kingmaker role.
The 2026 Senate race in Maine is a prime Democratic pickup opportunity in a challenging map. Sen. Susan Collins, 72, is seeking a sixth term after surviving narrow challenges in 2020. Maine’s ranked-choice voting system adds complexity, but Collins’ moderate image and committee clout—now chairing Appropriations—make her a tough incumbent. Democrats see Mills as the ideal foil: a battle-tested leader who could mobilize the base while appealing to centrists.
Mills has flirted with the idea for months but initially demurred, focusing on her final two years as governor. Recent events, including Trump’s second term and policy shifts on vaccines and tariffs, appear to have reignited her interest. She’s declined to criticize Collins directly, praising her earmark prowess while expressing broader concerns about Washington.
Democratic Recruitment and the Crowded Field
Democrats have eagerly courted Mills, viewing her as a stronger contender than other hopefuls. Senate Majority Leader Chuck Schumer and DNC officials have prioritized the seat, but recruitment has been tricky due to Collins’ popularity. If Mills enters, she could clear the field: Eight Democrats have already filed, including oysterman Graham Platner (endorsed by Sen. Bernie Sanders), former Rep. Jared Golden’s chief of staff Jordan Wood (who’s raised $1 million), and Maine Beer Co. co-owner Dan Kleban.
Platner, a political newcomer, launched his bid in August, emphasizing progressive priorities like climate action. Wood, leveraging his California connections, has traveled the state building support. Kleban’s entry last week came with a caveat: He wouldn’t confirm staying if Mills runs. Sanders’ endorsement of Platner adds tension, highlighting a generational divide within the party—leadership favors experienced figures like Mills, while progressives push fresh faces.
On the Republican side, Collins faces no primary threat yet, but her vote for RFK Jr. as health secretary has drawn scrutiny from the party’s right flank.
Polling and Strategic Outlook
Early polls show a competitive race. A June 2025 University of New Hampshire survey found Mills leading Collins 48%-45% among likely voters, with 7% undecided. Mills enjoys a net favorable rating of +10 in Maine, bolstered by her handling of post-pandemic recovery and opioid initiatives. Collins holds a +4 approval, but her support for Trump-era nominees has alienated some independents.
Betting markets like Kalshi give Democrats a slight edge (51% chance of holding the seat), but Mills’ entry could shift odds dramatically. Analysts predict a $100 million+ contest, with outside spending from groups like Senate Majority PAC and the NRSC flooding in. Maine’s split congressional delegation—Democrats hold the House seats—adds intrigue, as Rep. Jared Golden eyes a gubernatorial run.
Mills’ potential bid also ties into national dynamics: A win would help Democrats defend their slim Senate majority amid tough defenses in Ohio and Montana.
Reactions from Political Circles
Maine Democrats are buzzing with anticipation. “Janet Mills would be a powerhouse—experienced, tough, and electable,” said one party strategist. Progressives like Platner supporters worry she’d consolidate the field too late, diluting momentum. Republicans dismiss the hype, with Collins’ camp calling her “Maine’s most effective senator.”
Social media reflects the stakes: X users debate Mills’ viability, with #MillsForSenate trending locally. Critics question her age and progressive credentials, while supporters highlight her resistance to Trump as a selling point.
Impact on U.S. Politics and Maine Voters
For Mainers, a Mills-Collins showdown would spotlight key issues: Healthcare access, climate resilience (Maine faces rising seas), and federal funding—Collins’ earmarks brought $361 million home last year. It could boost turnout in a state where ranked-choice voting favors moderates, potentially influencing the gubernatorial race.
Nationally, the race is a bellwether for Democratic strategy in purple states: Recruit proven winners or energize the base? Amid Trump’s agenda, Mills’ entry could rally suburban women and independents, echoing 2020’s anti-Trump wave. Economically, it underscores Maine’s $70 billion economy, reliant on fisheries, tourism, and federal dollars.
For U.S. readers, this saga highlights the high-stakes 2026 midterms, where incumbency advantages clash with anti-establishment fervor.
Conclusion: A Decision That Could Reshape the Senate Map
Janet Mills’ staff interviews mark a critical step toward a Senate run, transforming speculation into action. As November approaches, her choice could unify Democrats and make Maine a marquee battleground.
If she jumps in, expect a fierce, issue-driven campaign against Collins. For now, the Pine Tree State watches closely—Mills’ move could tip the scales in Democrats’ uphill Senate fight.
