During the final Maine Senate debate on October 15, 2026, tensions escalated when Democrat Troy Jackson told incumbent Republican Senator Susan Collins to "shut up." The exchange occurred after a protester interrupted the debate, shouting concerns about artificial intelligence and data centers. The protester claimed, "AI data centers are destroying our climate. They are poisoning our water." Collins responded by suggesting the protester was affiliated with Jackson. Jackson countered, saying, "Oh, shut up ... I don’t even know that kid," before the debate continued and the protester was escorted out.
Polling data indicates a close race, with Jackson leading Collins by 1.3 percentage points according to the RealClearPolitics average. Collins has historically performed better than polls suggest. Recently, Jackson campaigned with Senator Bernie Sanders (I-VT) to garner support for his campaign. Jackson has faced scrutiny regarding his connections to the Democratic Socialists of America, as reported by The Daily Wire. In a previous debate, he was questioned about his support for Medicare for All, a policy associated with the organization, and his potential membership. While Jackson did not confirm or deny his affiliation, he emphasized his support for universal healthcare, stating, "I support Medicare for all, so that people that I know across the state have healthcare," and criticized pharmaceutical profits, Collins, and former President Donald Trump’s tax cuts. Jackson has attempted to distance himself from political labels, telling CNN’s Manu Raju that he doesn’t "consider myself anything" and informing MS NOW’s "Morning Joe" that he does not endorse the national platform of the Democratic Socialists of America.
