Former Maine Senate President Troy Jackson secured the Democratic nomination for U.S. Senate on July 25, 2026. Jackson replaces Graham Platner, who withdrew after sexual assault allegations, to challenge five-term Republican incumbent Susan Collins in a race that could determine control of the U.S. Senate.
The transition happened during a last-minute nominating convention in Bangor, where hundreds of delegates gathered to fill a vacancy created by the sudden exit of the primary winner. Maine Democratic Party Chair Charlie Dingman opened the proceedings with a sigh of relief
, signaling the party’s eagerness to move past a turbulent few weeks and focus on the general election.
The Displacement of Graham Platner
Graham Platner, an oyster farmer who won the Democratic primary in June, suspended his campaign after being accused of sexual assault by a former girlfriend in 2021. While Platner denied the allegations, he quit the race on July 10 after key supporters urged him to withdraw.
The vacancy triggered a never-before-used process under Maine law, granting the state party authority to name a replacement by Monday—99 days before the November 3 election. A flood of former governor candidates initially vied for the spot, but by July 19, most had abandoned their bids as support coalesced around Jackson.
Jackson’s victory was nearly absolute. He captured 566 of the 571 ballots cast. The only other remaining candidate, women’s health company CEO Saundra Pelletier, received five votes.
Troy Jackson’s Populist Platform and Political Roots
A logger from the town of Allagash, Jackson describes himself as a working-class fighter
. His political trajectory has been eclectic; he first ran for the Maine House of Representatives as a Republican in 2000, won as an independent in 2002, and switched to the Democratic Party in 2004. He later served as president of the Maine Senate from 2018 to 2024.
- Healthcare: Support for Medicare for All and the protection of Social Security and Medicare.
- Labor and Rights: Fighting to restore abortion rights nationwide and ensuring workers can organize unions without retaliation.
- Immigration: Calling for the abolition of Immigration and Customs Enforcement (ICE).
Jackson has already secured backing from Our Revolution and previously ran Maine operations for Bernie Sanders’ 2016 presidential bid.
The Strategic Battle for the 2nd District
For Democrats, Maine is a high-stakes opportunity. The party needs to net four seats to regain control of the Senate, and Maine is viewed as a primary target because President Donald Trump lost the state in 2024. However, Sen. Susan Collins remains a formidable opponent with a significant fundraising advantage and a tenure dating back to 1997.
Jackson’s appeal is specifically designed to penetrate rural strongholds. Strategically, a Democratic win requires narrowing the loss in the rural 2nd Congressional District to high single digits while maximizing turnout in cities like Portland.
The Collins campaign has already attempted to frame Jackson as a Bernie Bro
and a low-energy version
of his predecessor. Blake Kernen, a spokeswoman for Collins, noted that Jackson came in third in the Democratic primary for governor a month ago, suggesting his promises are empty.
Despite the campaign’s dismissal, early data suggests a competitive race. A University of New Hampshire Survey Center poll recently showed Jackson narrowly leading Collins 49% to 46%.
The 101-Day Sprint to November 3
Jackson now faces a compressed timeline. He must build a statewide infrastructure and raise millions of dollars in less than four months to compete on the airwaves. His primary challenge will be convincing the state’s large independent voting bloc and the more than 150,000 people who voted for Platner in the primary to align with his progressive vision.
At the convention, Jackson previewed his attacks on the incumbent, stating that for nearly 30 years Collins has told Maine she is concerned, but noted that concern does not lower the costs of groceries or gas, keep open the monitoring wards of rural hospitals like the one in Lincoln County, or restore rights she has taken away.

The race now moves toward the general election, with the first major hurdle being Jackson’s ability to translate his regional appeal in the north woods of Maine into a statewide victory by November 3.
