Maine’s 2026 Senate race between Republican incumbent Susan Collins and Democrat Troy Jackson remains a toss-up in recent polling, with surveys showing ties or narrow margins within sampling error as voters weigh state-level priorities against national dynamics. Collins draws crossover support from older voters and those focused on federal funding, while Jackson benefits from turnout among younger voters and those seeking change. In the open governor’s race, Democrat Hannah Pingree maintains a consistent double-digit lead over Republican Bobby Charles in aggregates and forecasts, reflecting stronger Democratic positioning in that contest. These patterns sustain elevated probabilities for a Democratic governor paired with either Senate outcome, while limiting prospects for Republican sweeps.
