Former Maine Senate President Troy Jackson (D-ME) won the state Democratic Party’s nomination for the U.S. Senate on July 25, 2026 [1].
Jackson's entry into the race comes at a critical juncture for the 2026 midterms. His candidacy is a direct effort by Democrats to unseat incumbent Republican Senator Susan Collins (R-ME) and flip a seat in the U.S. Senate.
The nomination follows the withdrawal of previous nominee Graham Platner from the race. This vacancy prompted the state Democratic Party to select a new candidate to lead their efforts in the November election [2], [3].
Jackson said he will defeat Collins in the upcoming general election. His campaign focuses on replacing the incumbent to shift the balance of power in the Senate [2], [4].
While some reports indicated the nomination process occurred on July 24, the primary announcement was recorded on July 25, 2026 [1], [5]. Jackson now steps into a high-profile contest against a long-serving incumbent in a state known for its competitive political landscape.

The selection of Troy Jackson represents a strategic pivot for Maine Democrats after the departure of Graham Platner. By nominating a former Senate President, the party is fielding a candidate with established legislative experience to challenge Susan Collins, whose seat is a key target for Democrats seeking to influence the composition of the U.S. Senate following the 2026 elections.
