Gideon in statistical tie with Collins

Salon -  Gideon leads Collins 43-42 in the survey, which has a margin of error of 3%. Fourteen percent of Maine voters remain undecided.

The Colby College poll finds that 54% of Maine voters have an unfavorable opinion of Collins, compared to 42% who have a favorable opinion of the senator.

Dan Shea, who chairs the government department at Colby College, told Maine Public Radio that the starkest trend is Collins' loss of support among women. Collins won past elections with more than 60% of women supporting her candidacy. More than 60% oppose Collins in the latest poll, and just 25% of women under 50 support her.
