Graham Platner Wins Maine Democratic Senate Primary in Pivotal Race

—Graham Platner won the Maine Democratic Senate primary, positioning himself as the party's challenger to incumbent Republican Susan Collins in a race that could determine Senate control. Platner's victory came despite a late wave of opposition attacks and questions about his background. Democrats debated internally whether a Senate majority was achievable with Platner at the top of the ticket in Maine, given Collins' persistent popularity. Trump quickly endorsed Collins after Platner's win, calling her a "sane woman." The race is expected to be among the most expensive and closely watched of the 2026 cycle.
