Susan Collins

Incumbent

The 2026 U.S. Senate election in Maine features six-term Republican incumbent Susan Collins facing Democratic nominee Troy Dale Jackson, former Maine Senate President, who was selected at a July 2026 Democratic convention following the withdrawal of primary winner Graham Platner due to sexual assault allegations. The race hinges on whether Jackson's working-class economic populism can rally Democrats and independents in Maine—the only state Republicans are defending that Kamala Harris won in 2024—or if Collins can maintain her traditional cross-party coalition by leveraging her seniority as Appropriations Committee Chair. Major election forecasters including Cook Political Report, DDHQ/The Hill, and Sabato's Crystal Ball rate the matchup as a Toss-up, while Inside Elections rates it Tilt Republican.

Supports economic populism and tax hikes on wealthy

Jackson runs on an economic populist platform aimed at reversing a system he views as rigged against working-class families. He advocates for raising taxes on billionaires and corporations, delivering tax cuts to workers, and protecting union organizing rights.

  • Tax billionaires and corporations to ensure they pay their fair share
  • Deliver tax cuts targeted directly at working-class Americans
  • Protect and strengthen the right of workers to organize and unionize

“Working people are getting crushed while billionaires and corporations buy power in Washington. I’ve spent my life fighting that same rigged system—from the logging woods to the Maine Senate. I’m running to carry forward Maine’s working-class movement, defeat Susan Collins and give people a senator who will fight like hell for them—not the wealthy and well-connected.”

“Tax the billionaires and make sure greedy corporations pay their fair share.”
