Maine Senate Primary Draws National Attention as Susan Collins Faces Graham Platner

Maine voters head to the polls Tuesday for a high‑stakes U.S. Senate primary that could influence control of Congress. Incumbent Republican Sen. Susan Collins, seeking a sixth term, is listed as a “toss‑up” by the Cook Political Report. Democratic challenger Graham Platner, an oyster farmer and military veteran, leads the Democratic field despite a series of personal controversies, including allegations of abusive behavior, sexually explicit texts, a Nazi‑linked tattoo and claims of undiagnosed PTSD. Former Gov. Janet Mills withdrew from the race in April citing funding shortfalls, leaving Platner as the de facto nominee. President Donald Trump has not endorsed Collins, and both candidates have raised substantial sums – Platner over $16 million and Collins more than $10 million, with contributions from pharma, aerospace and retail PACs. The primary also coincides with other Maine contests for governor and congressional seats, all conducted under the state’s ranked‑choice voting system.

The outcome will shape the Senate balance and reflects broader national debates over candidate standards, party strategy and the influence of controversial personal histories on electoral prospects.
