Graham Platner spoke to supporters after securing the Democratic nomination for U.S. Senate in Maine. He thanked the state for "having my back" and giving him grace in the wake of negative stories that had emerged. The military veteran and oyster farmer defeated Maine Governor Janet Mills (D), who suspended her campaign a month before the June 9, 2026 primary election, advancing to face five-term incumbent Senator Susan Collins (R) in the general election. The nonpartisan Cook Political Report with Amy Walter rated the general election race as a "toss up."
