The Troy Jackson Maine Senate race bid moved from long shot to front-runner in a single Saturday, as the logger and former state Senate president swept through county meetings across the state and built a delegate lead his rivals will struggle to close.

WISCASSET, Maine — Democrats here entered the weekend facing a compressed, improvised process to replace Graham Platner, whose campaign collapsed under scandal. By Saturday evening, the shape of the contest was no longer in doubt.

A Statewide Sweep

From Calais near the Canadian border to progressive Portland, in school gymnasiums and on Zoom calls spanning eight counties, Jackson’s operation simply outworked everyone else.

Maine Democrats selected 319 of 500 available delegate slots on Saturday. Candidates aligned with Jackson claimed a commanding share. Backers of former state CDC director Nirav Shah and Secretary of State Shenna Bellows accounted for only a handful each, based on a POLITICO review of released slates and elected delegate lists.

The margin was wide enough that Jackson announced plans to host a celebratory tailgate during Sunday’s caucus in York County.

The Ask That Preceded the Win

At a Friday rally beneath a gazebo in a Portland park overlooking the Atlantic, Jackson told more than 100 supporters that he wanted more than their votes. He urged them to organize, talk to neighbors, show up at county meetings, make calls, send texts, and pull additional people into the effort.

They did exactly that.

What Organization Looked Like on the Ground

Jackson’s team arrived at county conventions with structure most rivals lacked:

• Volunteer blocs wearing “Jackson for Maine” shirts left over from his unsuccessful gubernatorial run
• Printed flyers listing clear delegate slates
• A statewide phone operation that had already identified and placed supporters
• Volunteers drawn from more than a dozen unions backing his candidacy

That infrastructure was assembled in just eight days following Platner’s withdrawal — a genuinely difficult logistical feat.

From the Allagash to the Front of the Field

Jackson comes from far-northern Allagash and built his political career through organized labor. He has long allied with progressives and carried Bernie Sanders’ endorsement during his run for governor.

He also campaigned alongside Platner during the original primary. That changed quickly after POLITICO reported that a woman who had dated Platner accused him of sexual assault. Jackson called for Platner to leave the race. Platner denied the accusation and exited four days later.

Because Jackson’s policy record closely resembles the platform that carried Platner through the primary, he has been able to position himself as the natural inheritor of that coalition.

Why This Seat Matters

Whoever emerges from this improvised contest walks straight into national attention. Susan Collins is the sole Republican seeking reelection in a state Donald Trump lost in 2024, making Maine the most promising offensive target Senate Democrats have this fall.

Jackson does not underestimate what that means. Speaking to reporters in Augusta, he called it likely the biggest race in the country and described Collins as an unusually formidable opponent.

He is not wrong. Collins ranks among the strongest retail politicians in Congress, which is precisely why Jackson’s own person-to-person approach may matter.

Liam Kent, elected as a Jackson delegate in Lincoln County, said he applied while still undecided. Then Jackson called him directly. Kent said he was mid-sandwich when the phone rang and came away struck by how consistent Jackson sounded on the phone versus in person.

A Process Built in Two Weeks

The improvised nature of the caucuses produced predictable friction.

State and local Democrats designed the system in the fortnight after Platner’s exit. Staff at in-person and virtual meetings helped voters navigate problems with online ballots while campaigns adjusted to rules that were new to everyone.

Some delegate nominees appeared on multiple campaigns’ slates, though Jackson’s list showed less overlap than others. Bellows fielded enough nominees per county to cover alternate selections; Shah and Jackson did not, which left supporters in Hancock County uncertain where to direct extra votes.

State Rep. Nina Milliken, who coordinated Jackson’s Hancock County slate, initially found herself listed as a Shah delegate before his campaign removed her. She called the situation nonsensical and described the overall process as deeply messy.

The Cumberland County Prize

The biggest single haul came from Cumberland County, home to Portland and the densest concentration of Democrats in Maine.

Jackson-aligned candidates swept every nominating slot. Turnout in the online process ran high enough that the party extended voting hours. The final alternate slot ended in a tie, resolved by the county chair pulling names from a baseball cap.

Not Everyone Is Satisfied

The speed of the process left some Democrats feeling shut out.

Richard Zandler, 75, of Southwest Harbor ran as an uncommitted delegate and lost. He argued that campaigns assembled slates largely from donor lists and former staff, since every candidate had just come off a primary campaign.

There is evidence supporting him. One prospective Shah delegate said the campaign reached out specifically because he had donated to Shah’s gubernatorial bid.

Others complained about sheer volume. Roughly 3,700 Mainers applied to serve as delegates, and several reported receiving 20 or 30 calls and texts from competing campaigns. Shah said he personally placed around 500 calls before the weekend.

Some voters defended the party, noting it worked within a timeline dictated by state law.

Sunday and Beyond

Eight more counties will select 181 delegates on Sunday. An additional 101 Democratic state committee members are already chosen, and their preferences are harder to read since they were not elected on any slate. All told, 601 delegates will pick the nominee next weekend.

One important caveat remains: delegates are not formally pledged. Even those elected on a candidate’s slate can change their minds at the convention.

Shah, interviewed before Jackson’s dominance became fully apparent, said his campaign would keep its foot on the gas and predicted substantial persuasion ahead given that nobody is locked in.

Jackson, meanwhile, posted a video thanking supporters and telling them they had smoked it — adding that they were well on their way to getting the government they deserve.
