Graham Platner's apparent intention to withdraw from Maine's Senate race sets up a mad dash for Democrats to stand up a new candidate against Republican Sen. Susan Collins in a race that could decide which party controls the upper chamber.
The big picture: Democrats see Maine as one of a handful of seats they can realistically flip. But Platner's potential departure turns a top-tier pickup opportunity into chaos.
- Republicans hold the chamber 53–47. To take control, Democrats must flip at least four seats while defending the seats they already hold.
Driving the news: Platner announced Wednesday night he was suspending his campaign and plans to withdraw his candidacy.
- "The process needs to assure that what comes next is reflective of the Mainers who on June 9th turned out and showed that they are desperate for a different kind of politics," he said in a video posted to X.
- The announcement came shortly after he began bleeding support and lost endorsements from allies after an ex-girlfriend alleged Platner sexually assaulted her in 2021. Platner has denied the allegations.
- The assault allegation is the most serious in a monthslong run of controversies that had already eroded Platner's support with voters.
The fine print: Assuming Platner withdraws by July 13, a state Democratic political committee can replace him, but they must do so by July 27, under state law.
- His name will no longer be on the ballot in November.
- Neither state law nor the party's charter offers a clear playbook for what happens next, but party officials are considering a pop-up convention or a party-run caucus, per the New York Times.
- Officials have already ruled out having the state committee choose the nominee without voter input.
Between the lines: The last time Democrats swapped nominees on the fly, elevating Kamala Harris over then-President Biden in 2024, strategists argued skipping primaries made her a weaker candidate.
Zoom in: The deadline for independent candidates has already passed, but write-in candidates can still file.
- The filing deadline to become a write-in candidate for the general election is August 25, 70 days from Election Day.
Zoom out: Maine Gov. Janet Mills, whom Schumer recruited to run before she suspended her campaign against Platner ahead of the June primary, has so far demurred on running again.
- Former state Senate President Troy Jackson, who lost last month's gubernatorial primary, filed paperwork Tuesday to launch a Senate exploratory committee.
The bottom line: Regardless of Democrats' path forward, the moment puts new momentum behind Collins' re-election bid.
