Maine Senate Race Opens After Graham Platner Withdrawal; Troy Jackson Weighs Bid

Maine’s U.S. Senate contest shifted after Democratic candidate Graham Platner ended his campaign. Former state Senate President Troy Jackson, a logger and union member from northern Maine, has been discussed as a possible replacement.

Jackson was born in Fort Kent to a 16-year-old mother. He is a fifth-generation logger who began working in the woods as a teenager. In 1998 he participated in a union-organized logging blockade aimed at limiting the use of Canadian workers on Maine logging jobs. He later served in the Maine House and Senate, representing the rural St. John Valley.

Jackson was one of a small number of Democratic superdelegates who supported Bernie Sanders rather than Hillary Clinton in 2016. He has described his legislative priorities as focused on wages, employment stability, and opposition to certain trade practices that affect timber and manufacturing jobs. During his time in state government he backed measures related to labor standards and opposed some corporate tax incentives.

In 2022 Jackson sought the Democratic nomination for governor. He finished second in the primary. That same year he won re-election to his state Senate seat with 52.5 percent of the vote in a district where Donald Trump received a double-digit margin in the 2024 presidential election. Jackson has held office continuously since 2002.

Statewide data show that 36 percent of Maine adults hold a college degree, below the national average, with higher concentrations of degree holders in the Portland area. Jackson’s legislative district reports roughly 25 percent college attainment. He has won repeated elections in this region while maintaining support from several labor organizations, including endorsements during his gubernatorial campaign.

The Maine AFL-CIO has conducted member-to-member canvassing in past cycles for candidates with union backgrounds. Jackson has received backing from multiple state labor affiliates in previous races.

The general election would pit the Democratic nominee against Republican incumbent Susan Collins. Collins has won multiple terms in a state that has supported both parties in recent presidential and gubernatorial contests. Recent polling has shown her with an advantage over several potential Democratic opponents.

Democratic primary voters in the current cycle have shown support for candidates emphasizing economic policies aimed at rural and working-class communities. Jackson’s record includes consistent backing for such positions, though he has also faced criticism from some progressive groups over specific legislative compromises during budget negotiations.

Any replacement candidate would enter the race with limited time before the general election. Party officials have not announced a formal process for selecting a new nominee following Platner’s departure. Jackson has not confirmed whether he intends to seek the nomination.
