With Gov. Janet Mills out of Maine's 2026 Senate race, both Collins and Democratic challenger Graham Platner moved fast to define the contest on their own terms, per The Hill (May 7). The repositioning happened within days of Mills's exit reshaping the field.

Collins's first ad features Chris Gardner, executive director of the Eastport Port Authority, vouching for her constituent-service record — a deliberate choice. Eastport is remote, economically marginal, and the kind of place a senator highlights when the argument is 'I deliver for Maine, not for Washington.'

That's the Collins playbook in one image: incumbent competence, insulated from national Republican toxicity. Platner's counterprogramming will have to answer that frame directly, not just run against Trump. Mills's absence removes the strongest name-ID challenger; Collins is betting she can own the center before Platner builds his own.
