Maine Democrats had their dream candidate, until they didn't.
Graham Platner, a heavily tattooed, Marine Corps veteran and oyster farmer who built an insurgent, anti-billionaire populist movement, was supposed to be the one to finally unseat Susan Collins. He won the June 9 Democratic primary by an absolute landslide, taking 72.1% of the vote. Then, a devastating sexual assault allegation surfaced, and within days, his campaign crashed to the ground.
Now, the state party is facing an unprecedented scramble. With a state committee convention scheduled for July 25, 2026, to officially select a replacement nominee, a crowded field of candidates has rushed forward.
This isn't just a localized scramble to fill a vacancy. It's a fundamental fight for the soul of the state's progressive movement, with the national balance of power hanging in the balance.
Why the Platner Meltdown Leaves a Massive Power Vacuum
To understand why this race is so chaotic, you have to understand who Graham Platner was to Maine's left. He wasn't just a nominee; he was a phenomenon. He raised over $16 million, largely from small-dollar donors, running on an aggressive platform of Medicare for All, dismantling the "billionaire economy," and halting ICE operations.
His abrupt exit leaves a double-digit campaign account virtually locked up and a base of deeply passionate, but now deeply betrayed, volunteers and voters. Progresses are mourning the loss of a historic movement while trying to salvage its core ideas, while moderate Democrats are quietly hoping to steer the party back to a more traditional, "safe" general election footing.
Here is the actual lineup of Democrats vying to pick up the pieces, and what their candidacies tell us about where this race is heading.
The Left-Wing Torchbearers
For the progressives who backed Platner's policies but feel disgusted by his personal conduct, these candidates are trying to keep the populist fire burning without the heavy baggage.
Troy Jackson: The Blue-Collar Heavyweight
Former state Senate President Troy Jackson is the most formidable progressive in the mix. A fifth-generation logger from Allagash, Jackson is about as culturally authentic to rural northern Maine as it gets.
- The Pitch: Jackson has the backing of Bernie Sanders' political group, Our Revolution, and was quickly boosted by prominent national progressives like California Representative Ro Khanna. He's pitching himself as the natural heir to the progressive working-class coalition Platner built.
- The Catch: Jackson ran for governor earlier this year and finished a disappointing third in the June Democratic primary. He also carries a record of socially conservative votes from earlier in his career on abortion and marriage equality, which he has since recanted but which still causes some heartburn among progressive purists.
Paige Loud: The Outside Insurgent
At just 29, Paige Loud is a social worker who ran a left-wing primary challenge in Maine's 2nd Congressional District.
- The Pitch: Loud is offering no apologies and taking no prisoners. She was one of the first to demand Platner drop out and has openly slammed the party establishment. Her platform is uncompromisingly anti-imperialist, anti-corporate, and pro-worker.
- The Catch: She has virtually no institutional backing and finished last in her congressional primary's first round of ranked-choice voting. She's a long shot, but she speaks for a highly vocal segment of young activists who want a clean break from the party elite.
Jordan Wood: The Campaign Veteran
The 36-year-old Lewiston native and former chief of staff to Representative Katie Porter is making his second run at this Senate seat.
- The Pitch: Wood has deep structural experience in Washington but retains sharp progressive credentials. He's calling for Medicare for All and a highly aggressive campaign style to draw a sharp contrast with Collins.
- The Catch: He dropped out of the Senate primary last year to run in a House race, which he ultimately lost.
The Pragmatic Mid-Roaders
For Democrats who believe running a hard-left populist in November is a recipe for a Susan Collins blowout, these candidates represent a return to executive competence and broader statewide appeal.
Nirav Shah: The Pandemic Household Name
As the former director of Maine's CDC, Dr. Nirav Shah became a comforting, trusted face to hundreds of thousands of Mainers during the COVID-19 pandemic.
- The Pitch: Shah went on to serve as a high-ranking national CDC deputy director under the Biden administration. He has strong statewide name recognition and represents a highly polished, intellectual brand of progressive-leaning governance. In launching his bid, he pointedly reached out to former Platner supporters, aiming to bridge the party's painful factional divide.
- The Catch: Shah also ran in the gubernatorial primary this past June and lost. While he raised over $1 million, critics wonder if his administrative polish translates to the raw, populist energy needed to win a high-stakes Senate campaign.
Shenna Bellows: The Institutional Fighter
Maine's Secretary of State is no stranger to tough statewide spotlights.
- The Pitch: Bellows has served as a state senator and led the state's ACLU chapter. She's highly respected among mainstream Democrats for her staunch defense of voting rights and willingness to take on national political figures.
- The Catch: Bellows ran against Susan Collins back in 2014 and lost in a brutal landslide. More recently, she finished fourth in this June's gubernatorial primary. Her critics argue that party delegates shouldn't look backward to candidates who have already lost statewide races.
Dan Kleban: The Outsider Businessman
The co-founder of the highly successful Maine Beer Company is trying to position himself as the ultimate non-politician alternative.
- The Pitch: Kleban briefly ran for this Senate seat last year before stepping aside. He offers a pragmatic, economy-focused platform that blends climate change advocacy with small-business credibility.
- The Catch: Like Platner, he has never held public office. But unlike Platner, he lacks a pre-packaged grassroots populist army to carry him over the finish line.
What Happens Next
The state Democratic Party has a strict deadline: under state law, they must officially name their new candidate by July 27. The state committee's July 25 nominating convention will be the ultimate battleground.
Because this is a closed vote of party insiders and committee members rather than a public primary, backroom organizing and institutional relationships are going to matter immensely. Candidates who can successfully unite the mainstream party apparatus with the energetic remnants of the progressive base will have the upper hand.
Whoever wins the nomination will have to immediately pivot to a sprint against Susan Collins with practically zero runway.
If you're a Maine voter or a close follower of this race, look out for candidate debates or town halls over the next week. Keep a close eye on how local progressive organizations, labor unions, and county democratic committees split their support between Troy Jackson and Nirav Shah, as their choices will likely dictate the outcome on July 25.
