Maine Democrats Scramble to Replace Graham Platner Before July 27 Deadline in Race Against Susan Collins

Maine Democrats are racing against the calendar to choose a new candidate for one of the country's most pivotal Senate seats after primary winner Graham Platner abruptly ended his campaign, throwing the race against Republican Sen. Susan Collins into disarray.

Platner, an oyster farmer and Marine veteran whose insurgent, populist bid had energized the party's left, suspended his campaign Friday after a woman accused him of sexual assault, an allegation he has denied. The withdrawal came just days before the state's deadline to certify a nominee, forcing the Maine Democratic Party to activate a rarely used replacement process on an extraordinarily tight schedule.

Under state rules, Democrats have until July 27 at 5 p.m. to submit a new nominee. To meet that deadline, the party will hold a nominating convention on Saturday, July 25, at 9 a.m. at the Cross Insurance Center in Bangor, where roughly 601 delegates will vote to select Platner's replacement. County nominating meetings to elect those delegates are scheduled for July 18 and 19, compressing what is normally a months-long process into little more than a week.

A crowded field of prominent Maine Democrats has already stepped forward. Shenna Bellows, the secretary of state who challenged Collins in 2014, announced her candidacy, declaring that "the people of Maine have been building a movement that deserves to continue all the way to November when we beat Susan Collins." Troy Jackson, the former state Senate president whose gubernatorial ambitions had drawn backing from Sen. Bernie Sanders, entered within an hour of Platner's exit, vowing that "Maine deserves a senator that will fight for working families." Nirav Shah, the former director of Maine's Center for Disease Control and Prevention, is positioning himself as a more moderate alternative, while several others — including former congressional candidate Jordan Wood and Maine Beer Company co-founder Dan Kleban — are also vying for the nomination.

The stakes are enormous. Collins, first elected in 1996, is among the most vulnerable Republican incumbents on the map, and control of the Senate could hinge on the outcome. Democrats had viewed Maine as one of their best pickup opportunities before the Platner controversy scrambled their plans, and party strategists are now betting that a swift, orderly convention can steady the ticket before the general election campaign begins in earnest.

The unusual scramble also carries risks. A contested convention could expose divisions between the party's progressive and establishment wings just months before voters head to the polls, and Collins, a veteran of tough races who has repeatedly outperformed expectations, is certain to seize on any sign of Democratic disarray. Whoever emerges from Bangor will have barely three months to consolidate support, raise money and introduce themselves to a statewide electorate — a compressed timeline that leaves little margin for error in a contest that could help decide which party controls the Senate.
