Graham Platner secured the Democratic nomination for Maine’s U.S. Senate seat in the June 9 primary after Governor Janet Mills withdrew, defeating remaining opponents by a wide margin and advancing to face incumbent Republican Susan Collins in November. Despite earlier controversies over past online statements and a tattoo, Platner has repeatedly stated he will remain in the race, backed by strong progressive and grassroots support that showed little erosion in primary voting. Some national Democrats have expressed private concerns or called for his exit before the July candidate-replacement deadline, yet no formal pressure or health developments have emerged to alter his position. Traders therefore assign an 85.5% implied probability that he stays on the ballot through the midterms, reflecting the absence of any recent catalyst strong enough to force a withdrawal.
