Republican incumbent Susan Collins seeks a sixth term in Maine’s Class II Senate seat against Democratic nominee Graham Platner, an oyster farmer and veteran who secured the nomination with roughly 72% in the June 9 primary after Governor Janet Mills suspended her bid. Recent polls show a toss-up, with Platner holding narrow leads of 1–4 points in surveys from Quantus Insights, Tavern Research, and UMass Lowell conducted in early to mid-June. Maine’s use of ranked-choice voting, the state’s consistent Democratic presidential margins, and Collins’s exposure as the sole remaining Republican senator in New England contribute to trader positioning. Forecasters rate the contest a toss-up or slight Republican tilt, underscoring that late-cycle shifts in turnout or messaging on economic conditions and candidate familiarity could still alter the outcome before November.
