Troy Jackson’s Maine upset turns Susan Collins’s independence into a liability
Susan Collins’s defeat in Maine was more than a routine incumbent loss: it was a test of whether her carefully cultivated independence could survive a national backlash against Republicans and growing frustration over costs, war and abortion rights.

Democrat Troy Jackson, a former Maine Senate president and fifth-generation logger, defeated Collins after a campaign that Democrats reframed as a choice between working-class representation and a Washington establishment increasingly aligned with President Donald Trump. His victory gave Democrats their 53rd Senate seat and ended Collins’s five-term, three-decade career.

The result was especially striking because Collins had repeatedly won in a state that favored Democrats in presidential elections. She argued that her seniority and centrist reputation delivered federal money and practical concessions for Maine industries. Her campaign portrayed Jackson as an Augusta insider whose long career in state politics had done little to ease the affordability crisis.

Jackson’s supporters saw the same record differently. They argued that Collins’s occasional breaks with Trump could not outweigh her support for Supreme Court Justice Brett Kavanaugh, her votes on Republican priorities and her broader willingness to advance the administration’s agenda. Democrats also made abortion rights central to the race, while rising fuel prices, tariffs and the war in Iran widened opposition to the Republican ticket.

Both sides faced credibility problems. The Democratic campaign had only 101 days to recover after its original nominee, Graham Platner, withdrew amid allegations he denied. Collins, meanwhile, struggled to persuade voters that she remained a meaningful check on Trump. Jackson exploited that gap with a populist message, telling supporters, “Working people won,” and declaring, “I don’t owe them a damn thing.”

The conservative account presents the upset as a seismic political reversal but also emphasizes Collins’s record, the campaign’s corruption allegations and Jackson’s establishment backing after Platner’s collapse. The liberal interpretation is sharper: Maine voters rejected the limits of Collins’s moderation and demanded a more accessible, working-class senator. As one union leader put it, electing Jackson represented “an historic change.”
