Democratic Senate candidate Graham Platner of Maine ended his campaign on Wednesday after a series of controversies, including a sexual assault allegation, threw one of the tightest contests in the 2026 midterms into disarray.

The move by the ex-Marine and oysterman, announced in a social media video, is expected to hinder Democratic hopes of capturing Senate control in the November 3 elections, where Republicans hold a 53-47 edge.

Attention in Maine, viewed as a prime Democratic pickup chance, now turns to selecting a replacement to challenge Republican incumbent Susan Collins.

Democrats had already raised doubts about Platner's readiness before reports emerged of a woman accusing him of nonconsensual sex nearly five years ago.

Additional coverage indicated the woman claimed he entered her residence without permission and assaulted her while intoxicated, claims Platner has denied outright.

Further allegations surface involving past relationships and symbols

A report detailed claims from a former partner that Platner removed condoms without consent during intimate encounters, which his team labeled as false and driven by politics.

Party figures including Senator Bernie Sanders urged Platner to step aside.

Several lawmakers withdrew their support, and the Democratic Senatorial Campaign Committee indicated it would not fund the race with Platner still in it.

His exit may close a swift ascent fueled by progressive appeals for national healthcare, working-class priorities, and critiques of wealth concentration.

Other issues included past online posts he has apologized for and a tattoo once resembling a prohibited symbol that has since been altered.

Reports noted Platner's wife informed the campaign of explicit messages sent to others early in their marriage, though she later described their union as strong.

Platner has admitted to earlier missteps tied to alcohol and mental health struggles following service in Iraq and Afghanistan, seeking public understanding.
