A Democratic Senate campaign in Maine has collapsed after a rape allegation, bad news for Graham Platner and the grassroots movement that backed him.

• A former on-and-off partner accused Platner of raping her while he was blackout drunk, saying she complied out of fear for her safety.
• Top Democrats — Ro Khanna, Chuck Schumer, and the party's Senate campaign arm — pulled support and money, effectively ending his run against Susan Collins.
• Platner hasn't quit but posted a subdued response and is "weighing his path," a sharp retreat from his forceful denial of an earlier story.
• Volunteers who worked hard for him feel betrayed, partly because he told the Democratic caucus there were no more scandals coming.
• Attention is shifting to a replacement, with logger-turned-politician Troy Jackson favored by the grassroots and polling ahead of Collins.

Outlook: Platner has until around July 13 to drop out, and the party is scrambling over how to pick a replacement without handing the seat to Collins.
