Graham Platner won the Democratic nomination for Maine’s U.S. Senate seat on June 9 after Gov. Janet Mills suspended her campaign, setting up a general-election matchup against Republican incumbent Susan Collins. Despite recent scrutiny over past social media posts, a tattoo, and personal allegations, Platner has repeatedly stated he will not withdraw and maintains strong backing from progressive and grassroots voters, including endorsements from Sen. Bernie Sanders. Party insiders have discussed replacement options before the July 13 state deadline, yet no coordinated effort has gained traction. Traders price the chance he drops out before November at roughly 12–21 percent, reflecting his primary dominance and public resistance to pressure.
