Former Maine Senate President Troy Jackson secured the Democratic nomination for U.S. Senate on Saturday, July 25, 2026, in Bangor. Jackson replaces Graham Platner, who withdrew following sexual assault allegations, and will now challenge Republican incumbent Susan Collins in a race that could determine control of the U.S. Senate.
The transition happened in a whirlwind. Following a chaotic search for a replacement, Maine Democrats convened a last-minute nominating convention in Bangor to finalize their ticket. Jackson, a fifth-generation logger from Allagash, entered the room as the clear favorite after winning at least 481 of 500 delegates at county meetings held on July 18 and 19.
The final tally confirmed his dominance. According to reports from Nbcnews and boisestatepublicradio.org, Jackson captured 566 of the 571 ballots cast. The victory follows the withdrawal of several other candidates, including Secretary of State Shenna Bellows, former Maine CDC director Nirav Shah, former Congressional aide Jordan Wood, and Maine Beer Company co-founder Dan Kleban.
The Collapse of the Graham Platner Campaign
Jackson’s nomination is the direct result of a sudden void. Graham Platner, who had won the Democratic primary in June, withdrew from the race on July 10. His exit followed an allegation from a former girlfriend that he sexually assaulted her in 2021, a claim Platner has denied.
Troy Jackson’s Political Profile and Progressive Pivot
Jackson is a veteran of Augusta, having served as Maine Senate president from 2018 to 2024.
He is positioning himself as a working-class populist.
The GOP Strategy: Temperament and ‘Bernie Bros’
Republicans have wasted no time in defining their opponent. Sen. Susan Collins has characterized Jackson as a Bernie Bro
and asserted that his positions are clearly
in line with socialism. Her campaign spokesperson, Shawn Roderick, claimed Jackson is attempting to sell Mainers a multi-trillion dollar bill of goods
based on rhetoric that makes things sound free while being paid for by lower and middle-income workers.
The Senate Leadership Fund, the Republicans’ super PAC, has committed to spending over $42 million against him. This effort includes ads focusing on his temperament. The Washington Post reported instances of Jackson angrily throwing a water bottle during a meeting and shouting at a speaker of the state House until he was kicked out of her office.
Financials and the Path to November
Jackson faces a steep climb in terms of resources. With less than four months until the November 3 election, Jackson must rapidly scale his statewide operation.
Strategically, this race is a critical piece of the national puzzle. Democrats need to net four seats to regain control of the Senate. Because Collins is the only Republican representing a state President Donald Trump lost in 2024, Maine is viewed as one of the party’s best opportunities to flip a seat.
Both candidates hail from northern Maine, and both will compete to be the primary protector of the timber, potato farming, and lobster industries.
The High Stakes for Maine Democrats
Jackson’s challenge is now to unite a party that was recently energized by Platner’s grassroots surge. During his acceptance speech, Jackson acknowledged the need to earn trust, telling the crowd, there is a place in this campaign for all of you
.
Whether a logger from Allagash can convince the state’s large independent voting bloc to abandon a five-term incumbent remains the central uncertainty.
