Platner's disastrous candidacy exposes rifts that could dampen Democrats' Senate hopes

She is concerned, however, that it will be difficult for voters to coalesce around any new candidate in just three months.

"The thing I'm the most worried about is we run somebody and he or she loses, and then we spend the next four years pointing fingers at whose fault that was," she said.

In primary contests across the country this year, Democrats regularly opted for outsider congressional candidates offering a vivid vision for what the party should stand for and promising to fight for their beliefs in the face of Republican resistance.

Platner was one of the earliest and most prominent examples of this trend. With his gravelly voice, scruffy appearance and working-class back story, he gained a passionate following both in Maine and nationally.

He presented himself as a candidate who could advocate for liberal policies – like universal healthcare, wealth taxes, and low-cost housing – in a way that appealed to the kind of rural voters who have moved away from Democrats recently.

A win in November would have given Democratic progressives a chance to see blue-collar liberalism triumphing in battleground states like Maine.

And that, in turn, could have become a compelling argument for nominating a left-wing presidential candidate in 2028.

Now, that opportunity is likely dashed.

That Platner survived the series of scandals as long as he did was in part a testament to Democrats' hunger for a different kind of candidate. It also, however, underlined the risks of opting for charismatic political neophytes who haven't received close scrutiny before they run for higher office.

With Platner's exit, a group of more traditional candidates are already expressing interest in stepping in – including a handful who unsuccessfully ran for governor and one of the state's open House seats last month. They have recent campaign experience and some name recognition.

Troy Jackson, a former Maine Senate leader, campaigned side-by-side with Platner during his bid for governor, and came in third.

Nirav Shah, a state epidemiologist who gained prominence through regular public appearances during the Covid pandemic, finished a close second.

Shenna Bellows, the Maine secretary of state, is known for her lawsuit to block Trump administration attempts to gain access to state voter data. She was the party's nominee in 2014 but was soundly beaten by Collins.

According to Melcher, many Platner supporters will be hit hard because of the connection they made with their unconventional candidate. He believes they will ultimately back his replacement, however, because of the high stakes in this race.

Many Maine Democrats supported Platner with some reluctance because of his past scandals, he added, and this latest twist might end up a blessing in disguise for the party.

"If they play their cards right, I think that they will be fine and, with some voters, even better than they would have been before," he said, "as long as the party doesn't handle this in a way they see as disrespectful or a cabal taking things over."

The clock is ticking, however, and Collins awaits whoever emerges from whatever process Democrats ultimately follow. She has proven a formidable adversary for Democrats for 30 years, most recently defeating a better-funded opponent in 2020 despite polls showing her trailing right up to election day.

"It's not as though it was going to be easy before, and now it's hard," said Melcher. "Beating Collins was always going to be hard."
