A new SurveyUSA poll finds Congressman Jared Golden leading Republican challenger Austin Theriault by a double-digit 53-41 percent margin.

The survey is an outlier compared to previous polls that showed a tight race. The last poll had Theriault leading Golden by three points.

Polling released by the University of New Hampshire last week shows a deadlocked race in the 2nd District. The poll puts Golden at 45 percent to Theriault’s 44 percent, painting a picture of a much tighter race.

The SurveyUSA poll shows 6 percent of voters are undecided in the race. Golden leads by 30 points among seniors, but by just 4-5 points among those 35 to 64. Among those 18 to 34, the contest is tied.

Along party lines, 92 percent of Democrats favored Golden while 77 percent of Republicans chose Theriault. Theriault has a narrow 2-point advantage among those who have attended but not graduated college, while Golden leads by 12 among those with high school educations and by 24 among college graduates.

The race is expected to be close and is being closely watched nationally because it could impact which party controls the House of Representatives.
