In the open-seat race to succeed term-limited Gov. Janet Mills, trader consensus prices a Democratic victory at 90%, reflecting forecasters' Likely Democratic ratings from Cook Political Report and Inside Elections, alongside the party's trifecta control and consecutive gubernatorial wins in 2018 and 2022. Recent March polls underscore a competitive seven-candidate Democratic primary, with Nirav Shah surging to 31% in the latest Impact Research survey (Mar. 19–23), ahead of Troy Jackson (18%) and Shenna Bellows (17%), while Bobby Charles leads Republicans at 26% in Pan Atlantic polling. Absent general election matchups, odds hinge on ranked-choice primaries June 9; major shifts would require Republican consolidation or Democratic stumbles amid Maine's left-leaning electoral math for the office.
