2026 Maine Senate race
Coverage from Bangor Daily News, Politico, and others
The 2026 Maine Senate race is the contest between Republican Susan Collins and Democratic nominee Troy Jackson.
Its campaign has featured debate and town-hall planning, field organizing, and substantial spending by candidate-aligned and outside groups. Advertising and public arguments have focused on healthcare and Medicaid, abortion rights, energy costs, and candidates’ records and character. These issues, along with national party involvement, matter here as parts of the competition for Maine’s Senate seat.
The story now emphasizes the extraordinary scale of campaign advertising, with estimates near $259 million and negative ads dominating recent broadcast spending. The close polling picture remains unchanged.
The story has shifted from campaign spending and fundraising toward late-stage attacks over personal conduct and family, alongside Jackson's framing of the race as a referendum on Senate control.
New estimates put advertising in the race at record scale, with negative spots dominating a measured week. Jackson’s anti-billionaire messaging also drew sharper scrutiny after disclosures showed donations from at least four billionaires.
The financial picture now includes Jackson’s fundraising and campaign liabilities: he raised $20.4 million in his first three months, but ended September with less cash and vendor debt than Collins. Delayed disclosures and donor-transparency questions also became campaign issues.
New polling puts the race within a few points but offers no consensus on who leads, adding evidence of competitiveness. America PAC also emerges as a specific Collins-aligned spender, while coverage clarifies Collins’s differing votes on debate and final passage of the One Big Beautiful Bill Act.
Democratic nominee Troy Jackson is challenging Republican incumbent Susan Collins with a campaign emphasizing volunteers and direct voter contact, while Collins and Republican-aligned groups have substantially greater financial and advertising resources. Jackson raised $5.3 million through ActBlue in July, and Republican groups made major spending commitments against him; both campaigns and outside groups are also contesting issues including healthcare, reproductive rights, and taxes. The central test is whether Jackson can translate grassroots organizing and new fundraising into a competitive campaign against Collins’s established resources.
