Democratic challenger Troy Jackson led Republican Sen. Susan Collins 50% to 47% among likely voters in a Survey 160 poll of Maine’s Senate race conducted Oct 27 to Nov 1, while a late October Emerson survey put the five term incumbent at 50.6%. Among registered voters in the Survey 160 poll, Jackson held a 49% to 47% advantage, and Democrat Hannah Pingree led Republican Bobby Charles 53% to 41% in the gubernatorial race across both voter screens.
The mixed results followed a Nov 2 University of New Hampshire poll of Oct 27-31 likely voters that put Jackson ahead 54% to 45% and an Oct 26-29 YouGov survey showing him up 52% to 47%. Earlier late October polling from Marist gave Jackson a 49% to 47% edge among likely voters and a 53% to 44% lead among registered voters, a 7 point screen gap that pollster Nate Silver said Democrats were unlikely to suffer given high turnout indicators, while Big Data Poll director Rich Baris noted Jackson had built a large early vote lead.
