News of his win ignited audible excitement from Jackson volunteers at the meeting. One organizer sprinted across the school’s gym to show Jackson the news on their phone.
“It’s incredible,” Jackson told POLITICO moments after he secured a majority of delegates. “I’m excited, but very tempered, very measured about my emotions other than the fact that a lot of really great people made this happen.”
Jackson’s whirlwind path to the nomination is the prologue to an even tougher test. Collins has defeated well-funded Democrats of all stripes since she was first elected in 1996, and currently has an $11 million war chest in reserves, according to the latest filings from the Federal Election Commission.
And Jackson’s last-minute ascension puts him at an even greater disadvantage: Maine’s nominating convention on Saturday is just 101 days before Election Day in November, giving Jackson less time to run against Collins than Harris had in her losing campaign against Donald Trump in 2024.
“We’re going to have to put our ground game even more into maximum overdrive,” Jackson told reporters after his Sanford rally, referencing Platner’s large number of town halls and his short timeline. “What did Graham have, 70 town halls? If we did one every other day we wouldn’t be able to do 70 from here on out.”
Jackson also said he will have to quickly introduce himself to the southern part of the state, given he hails from the far-north and represented the area in the state Senate.
“I’m not as well known down here,” he said. “I’m six hours away from my home. And as we know, the state legislature means nothing. Nobody’s following it. It’s a lot of work to make sure people know what I’m about.”
Many former Platner supporters were part of the team of volunteers, organizers and delegate nominees that whipped votes for Jackson’s delegate slate in counties across Maine over the weekend. The strength of his organizing operation helped Jackson jump out to a commanding lead after Saturday’s meetings, including a sweep of all 149 delegates in Cumberland County, the largest county in the state.
Travis Jones, a former Platner supporter from Seal Harbor, Maine, who was elected as a delegate alternate in Hancock County, where Platner lives, said he’s backing Jackson because of the similarities between Platner’s progressive agenda and the Jackson campaign.
“I was a big supporter of the previous candidate, Graham Platner. I really liked his policies. Troy mirrors a lot of those,” Jones said ahead of the delegate meeting in Ellsworth, Maine, on Saturday. “The previous campaign really energized me, and here I am today.”
