Scoop: Republicans prepare $8 million ad blitz against Platner replacement

Republicans are preparing to welcome a potential Graham Platner replacement in Maine's Senate race with $8 million in negative ads, aiming to introduce a new Democratic nominee to voters on their own terms before Democrats can.

Why it matters: Republicans are doing something Democrats wish they could: Move on from Platner.

• The progressive candidate, who said Monday he is taking time to "reflect" on his next steps, remains officially in the race and is looking to leverage his status as the Democratic nominee to influence who could replace him.
• Republicans, meanwhile, see an opening: three weeks to prepare a campaign against a Democratic nominee who will have little time to introduce themselves to voters.

Driving the news: Pine Tree Results, the super PAC backing Republican Sen. Susan Collins, raised $10.5 million during the first half of the year — matching what it raised during the same period in 2025, according to a person familiar with the matter.

• The group pulled its anti-Platner ads Tuesday and has $8 million in cash on hand to define a likely fresh Democratic nominee for voters during a compressed campaign.
• Among the donors to the pro-Collins super PAC is Blackstone president Jon Gray, a longtime Democratic donor. He contributed $250,000 well before Politico and CNN reported sexual assault allegations against Platner.

What we're hearing: Platner appears to be using whatever sway he might still have to try to choose his successor.

• "Graham still has to make the decision to leave the ballot. And folks are pretending that he has. And he has not," a person familiar with the campaign's internal discussions said Tuesday morning. "[It's] very clear that he cares about the movement more than the party."
• Another person close to Platner's adviser, Morris Katz, said Katz has discussed suspending the campaign with Platner and planned to meet him in Maine on Tuesday to tell him it's not a question of whether he drops out, but when.
• The same person said Platner has told his team that he built a movement and won a record-breaking number of votes, and that he does not want his successor to be a "corporate" Democrat.

Between the lines: There have been conflicting accounts of the behind-the-scenes maneuvering.

• The New York Post reported Tuesday that a source said Katz is "still recommending Platner stay in the race." Katz responded on X that "no one in campaign deliberations or familiar with my thinking is talking to" the Post.

Zoom out: Platner's implosion in Maine is scrambling the spending calculus for both parties, with consequences that could stretch as far as Alaska.

• Senate Majority PAC, the Democratic super PAC aligned with Senate Minority Leader Chuck Schumer (D-N.Y.), has publicly paused its spending in Maine to pressure Platner to exit the race.
• If Platner stays on the ballot, the $33 million that the super PAC has reserved for Maine would likely be redirected to emerging Democratic pick-up opportunities, including Iowa, Ohio and Alaska.

The intrigue: That shift could benefit Senate candidates such as former Sen. Sherrod Brown in Ohio and former Rep. Mary Peltola in Alaska.

• Progressive energy is also likely to flow toward Abdul El-Sayed's Senate campaign in Michigan, where he is in a high-stakes showdown with Rep. Haley Stevens for the Democratic Senate nomination.

The bottom line: Platner's indecision is fueling anxiety throughout the Democratic Party and exposing a divide between progressives and the party establishment that leaders had hoped to bridge before November.
