Can Trump End Susan Collins’s 30-Year Winning Streak in Maine?

Republican Senator Susan Collins of Maine has not faced a genuinely competitive election in three decades, but the political climate under President Donald Trump could change that. Collins, known for her moderate brand and occasional breaks with her party, now finds herself navigating a deeply polarized environment where Trump’s influence looms large. While corruption allegations have surfaced, they are not her primary vulnerability; instead, it is her association with a president who is deeply unpopular among many Maine voters. The state, which has a history of independent-minded politics, could see a shift if Democrats and independents mobilize against the Trump agenda. Collins’s ability to distance herself from Trump while retaining Republican support will be critical. With the 2026 midterms approaching, her political future may hinge less on her own record and more on the national mood. A defeat would mark a stunning end to one of the Senate’s longest-serving careers.
