Maine Democrats scramble to replace Platner in crucial Senate race

Graham Platner’s Senate bid collapsed after a sexual assault allegation, forcing Maine Democrats to line up a substitute nominee for a race that could help decide control of the U.S. Senate. The Maine Democratic Party voted on July 8 to hold a nominating convention of about 600 delegates, racing a July 27 deadline under state law.

Platner, an oyster farmer and Marine Corps veteran, won the June 9 Democratic primary with 156,084 votes, or 72.1%, according to certified results. Janet Mills, the former governor who had been his main rival, finished with 41,644 votes, or 19.2%. The scale of that victory had briefly made Platner look like the Democrat most likely to turn Susan Collins’s Senate seat into a top pickup opportunity.

Instead, the campaign became a national flashpoint as questions about Platner’s past spread and Donald Trump attacked him publicly, calling him a “thug.” Platner announced on July 8 that he would withdraw or suspend his campaign after the allegation surfaced, leaving Maine Democrats with less than four months before the Nov. 3 general election to install a new nominee and rebuild a statewide operation.

The replacement fight carries unusually high stakes because the Maine seat is one of the few that could alter Senate control. Collins, the Republican incumbent, remains the central obstacle for Democrats in a state that has often rewarded local identity and independent politics. Platner’s rise suggested that a progressive outsider with military service and working-waterfront credibility might overcome that barrier; his collapse showed how quickly a candidate can be lifted and then engulfed by the same national forces that now shape even small-state contests.

That pressure has been visible inside the party as well. Maine Democrats and national Democratic groups have disavowed Platner, while some state officials pushed for him to step aside. The convention vote was designed to give the party a formal path to choose a substitute before the July 27 deadline, but it also underscored how little time remains to define the next nominee, raise money and reset the race before November.
