With Graham Platner as likely Democratic nominee, Maine voters grapple with their choices

Maine’s U.S. Senate race has narrowed to a contest between Republican incumbent Susan Collins and Democratic nominee Graham Platner, after Governor Janet Mills suspended her campaign in April. Platner, a Sullivan oysterman and military veteran, has surged in polls, positioning himself as the strongest Democratic challenger to Collins, who has long held seniority in Congress. Collins has relied on her ability to deliver federal funding to Maine, a strategy that has defied past polling trends and secured her re-election. However, Platner’s campaign accuses her of enabling policies under President Donald Trump, including healthcare cuts and conflicts that have driven up gas prices, framing her as out of touch with Mainers’ daily struggles. Platner’s ads directly challenge Collins, stating her ‘performative politics’ are disqualifying for the role. Some Democrats, including former supporters of Mills, have rallied behind Platner, citing his potential to deliver results and regain Senate control. U.S. Senate Minority Leader Chuck Schumer endorsed Platner, shifting from his earlier support for Mills. Yet, divisions persist, with some Democrats questioning whether a unified push to oust Collins will be enough to overcome Collins’ established record. Registered Republicans like Shane Hill, though not Trump supporters, remain skeptical of Platner’s chances, believing Collins’ experience and seniority will secure her victory. Meanwhile, Collins’ campaign continues to focus on her track record of bringing federal dollars to Maine, avoiding direct mentions of Platner in recent ads. The June 9 primary will determine whether Platner solidifies his position as the Democratic nominee to face Collins in the general election. Mills, who suspended her campaign due to lack of funds, has not endorsed Platner or his competitor, David Costello, though she has ruled out supporting Collins. South Portland Mayor Elyse Tipton, a former Mills supporter, now sees Platner’s strength as a leader but remains focused on the broader goal of regaining Democratic control of the Senate. The race reflects broader tensions within Maine’s political landscape, where voters are weighing Collins’ institutional authority against Platner’s challenge to Trump-aligned policies.
