Incumbent Democrat Chellie Pingree holds a consistent double-digit lead over Republican Ronald Russell in Maine’s 1st district, with the latest University of New Hampshire poll showing 57% to 35%. The district’s D+11 partisan lean, Portland-area base, and Pingree’s long incumbency underpin forecaster ratings of solid or safe Democratic. Maine’s ranked-choice voting means first-round margins depend on initial vote shares before any transfers. Trader pricing concentrates probability on Democratic margins of 25-40 points while assigning minimal value to a Republican win, reflecting the absence of recent polling shifts or major campaign developments that could compress the gap before November.
