Republican Sen. Susan Collins of Maine is making federal spending a centerpiece of her campaign for a sixth term, emphasizing the $1.5 billion in congressional funding she has directed to nearly 700 local projects during her tenure as chair of the Senate Appropriations Committee. The veteran lawmaker faces Democratic challenger Graham Platner in what promises to be one of the most closely watched Senate races of 2026, with control of the chamber potentially hanging on the outcome.
Collins became the first Maine senator in more than nine decades to hold the key budgeting position when she assumed the Appropriations Committee chairmanship. At a recent manufacturing summit in the state, she described the post as a "once in a century" opportunity and made clear she intends to campaign heavily on her ability to bring federal dollars directly to Maine communities.
What the Right Is Saying
Collins has argued that her Appropriations Committee chairmanship represents an irreplaceable asset for Maine that would disappear if voters elect a freshman senator. "It took me years to climb the ladder of seniority," she told attendees at the manufacturing conference. "And that will go away with a freshman senator." She pointed to specific accomplishments including funding for community colleges, trade profession incubators, and biomedical research initiatives with a foothold in Maine.
The Republican incumbent also highlighted her opposition to Trump's tariffs on Canadian products, describing how she lobbied senior administration officials to protect a paper mill near the Canadian border that relies on pulp and steam from facilities across the frontier. "But think how devastating that would have been for northern Maine," Collins said.
National Republicans have rallied behind Collins despite occasional frustration with her centrist voting patterns. Vice President Vance acknowledged during an event in Bangor, Maine: "Sometimes I get frustrated with Susan Collins. I almost wish that she was more partisan." He added, "But the thing I love about Susan is she is independent, because Maine is an independent state."
What the Left Is Saying
Graham Platner, a combat veteran and oyster farmer who emerged as the likely Democratic nominee after Gov. Janet Mills suspended her campaign last month, has dismissed Collins' federal spending achievements as insufficient compared to what she could deliver if not beholden to corporate interests. "I was told — essentially my entire life actually — that one day Susan Collins was going to get the gavel on Appropriations, and when that came, Maine was going to see a boon of riches," Platner said during a town hall at Bowdoin College in April. "Well, that never materialized."
Ben Chin, Platner's campaign manager, argued during an April press call that Collins bears responsibility for Mainers' financial struggles given her role overseeing the federal budget. "Every time Sen. Collins leverages a little bit of an earmark to build a bridge or a road, that just does not make up for the fact that Mainers right now are hemorrhaging money left and right because she has backed the Trump administration's agenda to bleed people dry," Chin said.
Platner has repeatedly characterized Collins as providing "symbolic opposition" to Trump's agenda, part of what he calls "performative politics" typical of a Congress that enriches the wealthy at the expense of working-class Mainers. He also criticized her for providing a key vote advancing Trump's One Big Beautiful Bill before ultimately voting against it. The legislation includes cuts to Medicaid, the health insurance program that covers roughly 30% of Maine's 1.4 million residents.
What the Numbers Show
According to figures from Collins' office, she has secured $1.5 billion in congressional spending over five years directed to nearly 700 local projects across Maine. Her campaign's first advertisement highlighted funding for a breakwater dock in Eastport, a town with a population of just over 1,000 residents.
Collins' electoral coalition has shifted significantly over the past decade. In 2014, she won reelection with nearly 70% of the vote. By 2020, that share had dropped to 51%, as Democrats attempted to tie her to an unpopular President Trump and a pandemic-affected economy. Maine's electorate includes a substantial independent voter population, typically representing around one-third of voters.
The return of congressional earmarks in 2021, reinstated when Democrats controlled both chambers, has provided Collins with additional resources to direct federal funding to her state. She has also cited funding to control the spruce budworm, a caterpillar that periodically devastates Maine's softwood timber industry.
The Bottom Line
The Maine Senate race illustrates the tension between incumbency advantages rooted in constituent service and newer electoral dynamics emphasizing ideological contrast and opposition to the national party in power. Collins is wagering that her ability to deliver direct federal benefits to small communities will outweigh Platner's arguments about systemic political dysfunction and insufficient resistance to Trump administration policies.
Independent voters are expected to once again play a decisive role in November, as they did in 2020 when Collins narrowly secured reelection. The race could prove pivotal for Senate control, with both parties investing significant resources in what promises to be one of the cycle's most competitive contests. Voters will ultimately decide whether pork barrel politics and federal spending translate into electoral support or whether calls for political transformation resonate more strongly with a changed Maine electorate.
