Troy Dale Jackson, a progressive Democrat from northern Maine, is mounting a challenge to unseat Republican Senator Susan Collins in one of the nation’s most closely watched Senate races. Jackson, 58, who has served multiple terms in the Maine Legislature and as Senate president until term limits ended his tenure in 2024, faces the difficult task of persuading voters to replace Collins, a 73-year-old centrist who has long secured federal funding for Maine.

Jackson’s political persona sharply contrasts with Collins’s measured style. Known for his blunt and sometimes combative approach, Jackson has drawn both admiration for his authenticity and criticism for his temperament. Colleagues have cited instances where he could be confrontational or dismissive, including clashes with Maine’s Governor Janet Mills, a moderate Democrat who has not endorsed him in the race. Jackson did not seek Mills’s endorsement, and his campaign declined to comment on their relationship.

Born and raised in the remote town of Allagash near the Canadian border, Jackson’s roots are deeply working class. A fifth-generation logger, he credits a 1998 blockade at the Canadian border over logging rights as his political awakening. His early political career saw him switch from Republican to independent and then to Democrat, reflecting his evolving views. He has abandoned socially conservative stances common in his rural base to embrace progressive policies, including abortion rights, expanded child care subsidies, paid family leave, and free school meals.

Jackson’s record is multifaceted; while he successfully championed progressive initiatives, some efforts faltered amid legislative disputes, and his inability to manage frustration publicly has drawn scrutiny. An incident in 2021 involved him throwing a water bottle during a dispute over a prescription drug price bill. More recently, a decades-old police report surfaced regarding a 1988 altercation with a man and allegations of pushing his then-girlfriend. Jackson accepted responsibility for the fight but denied any violence toward his partner, Lana Pelletier, with whom he has two adult sons.

Collins has referenced these incidents to question Jackson’s temper and personal life, including a comment about Pelletier being his second cousin, which Jackson’s campaign condemned as a personal attack. Jackson responded by criticizing Collins’s record and her attempts to divert attention from policy issues to his personal background.

Jackson campaigns on labor support, highlighting endorsements from numerous unions and emphasizing his working-class authenticity. His modest lifestyle and background as a logger and labor organizer distinguish him in a Senate field largely composed of career politicians. Despite his grassroots appeal, he struggles with name recognition statewide, a challenge intensified by a significant Republican advertising advantage; Republicans have spent or reserved nearly $88 million in campaign ads since July compared to $60 million by Democrats.

His strategy strives to undercut Collins’s image as an independent representative of Maine by portraying her as aligned with former President Donald Trump and wealthy interests. While Jackson’s plain-spoken manner resonates with some voters, others question his lack of traditional political charisma.

Jackson’s campaign faces a critical test in a state that has never supported a Trump presidential bid, where economic concerns and political independence continue to shape voter attitudes. As the race moves forward, the contest between Collins’s established presence and Jackson’s insurgent candidacy will likely remain one of the most closely watched and hard-fought Senate battles of the election cycle.
