Troy Jackson Secures Democratic Nomination for Maine U.S. Senate

Former Maine Senate President Troy Jackson has effectively secured the Democratic nomination for the U.S. Senate after a dominant performance in county nominating meetings held across Maine on July 19, 2026. Jackson garnered the support of approximately two-thirds of the 601 convention delegates, including a sweep of preferred delegates in Cumberland County and a strong showing in Kennebec County.

This surge of support led four primary opponents to suspend their campaigns on July 19 and 20: Secretary of State Shenna Bellows, former public health chief Nirav Shah, brewer Dan Kleban, and Jordan Wood. Shah and Wood formally endorsed Jackson, while Bellows cited the need for party unity and the importance of her official duties as Secretary of State. Kleban noted that the county meetings indicated he lacked a viable path forward.

The vacancy was created after primary winner Graham Platner withdrew on July 8 following allegations of sexual assault. To meet a state deadline of July 27, the Maine Democratic Party scheduled a nominating convention for July 25 at the Cross Insurance Center in Bangor to officially name the nominee.

Jackson, a progressive focused on labor rights and economic populism, has received support from the organization Our Revolution and is currently considering an endorsement from the Maine chapter of the Democratic Socialists of America. He now faces Republican incumbent Senator Susan Collins in the November general election with approximately 101 days to build his statewide campaign.
