Platner ally Troy Jackson locks down delegates as top rivals for Democratic Senate nomination drop out

Former Maine Senate President Troy Jackson appears to have locked up enough delegates to win the abbreviated race to replace now ex-candidate Graham Platner as the Democratic Senate nominee in the high-stakes showdown to face off with longtime Republican Sen. Susan Collins.

Delegates aligned with Jackson won the vast majority of the 500 slots that were up for grabs on Saturday and Sunday as Maine's 16 counties held two days of delegate selection for next weekend's nominating convention. And Jackson's top two rivals for the nomination, Maine Secretary of State Shenna Bellows and Nirav Shah, a former top public health official, dropped out of the race on Sunday.

"In November, Mainers will defeat Susan Collins, and we will take back our Senate seat from the billionaires and corporations who think they own it," Jackson said in a social media post Sunday evening.

While the delegates on Jackson's slate are not required to support him at next weekend convention, he is in an extremely strong position to secure the nomination and face off in the midterm elections against Collins in what's expected to be a combative and expensive ballot box battle that's among a dozen nationwide which will determine if the Democrats can win back the Senate majority. The GOP currently holds the chamber 53-47.

A fifth-generation logger and a one-time conservative Republican who became a Democrat over two decades ago, Jackson came in third place last month in Maine's Democratic gubernatorial primary.

On Saturday, in the race to replace Platner, Jackson-aligned delegates won more than 90% of the slots, including all 149 in Cumberland County, Maine's most populous county and home to the state's largest city, Portland.

"Yesterday was an unbelievable huge step, but our work is not finished — not even close," Jackson said Sunday morning. And the winning streak of Jackson-aligned delegates continued throughout the day.

The 500 delegates elected this weekend will join 101 delegates coming automatically from the Democratic State Committee. All 601 will vote for the Senate nominee at next Saturday's convention in Bangor, Maine.

Bellows, who unsuccessfully ran for the Democratic gubernatorial nomination, exited the Senate sprint on Sunday morning.

"Donald Trump’s attacks on our democracy are only accelerating, and the best way that I can serve our state and country at this moment is by focusing exclusively on my role as Secretary of State," Bellows said in a statement that didn't mention Jackson.

Shah, a former director the Maine Center for Disease Control and Prevention from 2019 to 2023 who later served as principal deputy director of the federal CDC during then-President Joe Biden's administration, and who came in second in last month's Democratic gubernatorial primary, dropped out Sunday evening and backed Jackson.

"To Maine Democrats: Susan Collins will not be defeated without a united Democratic Party. And we cannot unite without treating one another with respect," Shah wrote in a statement. "No matter whom you supported in this race, I urge us all to remember that in the weeks ahead."

Jackson, in a social media post, thanked Shah and urged, "Now it's time for all of us to come together, build the broadest possible coalition, and defeat Susan Collins. Let's get to work."

Another Senate candidate, Maine Beer Company co-founder Dan Kleban, also announced a campaign suspension on Sunday.

MAINE DEMOCRATS RALLY BEHIND PLATNER'S PLATFORM IN SPRINT TO REPLACE HIM

Along with Platner, Jackson had the support of progressive champion Sen. Bernie Sanders of Vermont as he ran for governor, and he is currently backed by 'Our Revolution,' the group born in 2016 out of Sanders' first presidential campaign.

Jackson, similar to Platner, is running on a progressive and populist platform aimed at working-class voters. He backs raising taxes on billionaires, the universal healthcare system known as "Medicare-for-all," abolishing U.S. Immigration and Customs Enforcement, and he opposes military aid to Israel at a time that Democrats are increasingly divided on support for America's longtime Middle East ally.

Platner, a combat veteran and oyster farmer who was backed by Sanders soon after he launched his bid last August, saw his campaign quickly catch fire. Two-term Democratic Gov. Janet Mills, who was heavily recruited by longtime Democratic Senate leader Sen. Chuck Schumer to run for the Senate, suspended her campaign this spring after trailing Platner in fundraising and in the polls.

THE TWELVE RACES THAT WILL DETERMINE THE SENATE MAJORITY

But even as Platner steamrolled the Democratic establishment and crushed the competition last month to capture the nomination, he had already been forced on defense in the wake of a slew of scandals.

Platner dropped out earlier this month, amid calls from top Democrats in Maine and across the country to immediately exit the race following an explosive report containing an allegation of rape from a woman he previously dated. Platner denied the report but stepped aside.

While Jackson was among those who quickly called on Platner to end his bid in the wake of the rape allegation, he had previously campaigned alongside Platner and made the case that he was the best candidate to continue the fight for the progressive and populist agenda.

"This movement has always been bigger than one person. It's about taking on a system rigged against working people, fighting for ‘Medicare-for-all,’ strong unions, higher wages, reproductive freedom, and an economy where billionaires and corporations finally pay their fair share," Jackson said last week during a Our Revolution virtual town hall, as he pointed to Platner supporters.

At last week's first debate among the replacement candidates, Jackson pointed to Platner and said, "That's the thing that I think Graham did the best: talked about fighting against the health care industry and the prescription drug industry to make sure that people in this state and this country have affordable, quality health care."
