The high-stakes Senate race in Maine is shaping up as a referendum on whether voters value Sen. Susan Collins’ ability to deliver federal money more than Democratic challenger Graham Platner’s promise to upend a system he says favors elites over working people.
Platner, whose insurgent campaign helped prompt Gov. Janet Mills to suspend her bid, has campaigned on a call for a political revolution and sharp critiques of establishment politics. Collins, meanwhile, is emphasizing a traditional incumbent strategy: using her seniority and committee power to bring projects and grants back to Maine.
Central to Collins’ argument is her new role as chair of the Senate Appropriations Committee — the first time a Maine senator has chaired that influential panel in more than 90 years. She has described the position as a rare opportunity and plans to make it a centerpiece of her reelection pitch, arguing that Maine would lose direct access to federal influence if voters replace her with a freshman senator.
Her campaign’s opening ad showcased a small Eastport breakwater project as an example of how even modest investments matter to local communities. Collins’ remarks at a state manufacturing summit listed other wins: funding for community college workforce programs, restored federal support for biomedical research, pest-control money to protect softwood timber from spruce budworm, and advocacy against tariffs that would have harmed cross-border paper mill operations in northern Maine.
Collins’ office says she has secured about $1.5 billion in congressional spending over five years for nearly 700 local projects — a return to the earmark-style spending that older incumbents have long used to shore up support.
Platner and his team seek to undercut that case by arguing the spending doesn’t offset what they see as broader policy failures. Ben Chin, Platner’s campaign manager, has framed Collins’ earmarks as insufficient when weighed against her votes and positions that, they say, aligned with an agenda that has hurt ordinary Mainers. Platner has accused Collins of offering only symbolic opposition to national policies he blames for economic pain, calling much of Washington’s work “performative politics.”
He and other critics point to Collins’ vote that advanced a major package that included cuts to Medicaid— a concern in a state where roughly 30% of residents rely on the program — and argue her centrist image masks deference to corporate and elite interests.
The race will likely hinge on independent voters, who have been decisive in past Maine contests. Collins has historically performed well with unaffiliated and split-ticket voters: she won overwhelmingly in 2014 and narrowly in 2020. Political observers say her tradition of delivering visible local projects resonates with independents, but they caution that national headwinds for Republicans could make 2026 different.
Republicans nonetheless see Collins as essential to keeping the Senate majority, and party leaders have increasingly muted earlier criticisms of her. Recent comments from national figures — including the vice presidential campaign and former President Trump, who has shifted from earlier denunciations to saying he hopes she wins to help retain a Republican majority — underline how much is at stake for control of the Senate.
As the campaign moves toward November, the central question for Maine voters will be whether tangible federal investments and the promise of influence in Washington outweigh Platner’s charge that the political system is rigged and in need of fundamental change.
