Maine's 2026 Senate and gubernatorial contests feature closely matched contenders in a state with a history of split-ticket voting and independent influence. Democrat Hannah Pingree holds a consistent double-digit polling lead over Republican Bobby Charles in the open governor's race, with independent Rick Bennett drawing single-digit support. The Senate matchup between Republican incumbent Susan Collins and Democrat Troy Jackson remains far tighter, with recent surveys showing Jackson ahead by a few points among registered voters amid notable anti-incumbent and national political crosscurrents. These patterns sustain trader focus on a Democratic sweep as the plurality outcome while elevating split-ticket possibilities, particularly given Collins's long record of appealing to moderates and Jackson's positioning on state issues. Late-cycle polling shifts, turnout among independents, or campaign events could widen gaps between the races before November.
