SurveyUSA conducted a sampling of 779 likely voters in Maine for Colby College and The Boston Globe via phone interviews and online surveys from Sept. 4-10. It has a 3.6 percent margin of error.

“Mainers for the first time in a while are going to have to pay attention to the statewide race for president,” said Dan Shea, a political science professor and director of the Goldfarb Center at Colby College. "The Clinton campaign can no longer take this state for granted.”

Multiple recent polls have shown a closer fight between Clinton and Trump at both the national and state levels.

Several surveys earlier this year, for example, had Clinton topping the GOP presidential nominee by scores ranging from 7 percent to 10 percent in Maine.

A Washington Post/Survey Monkey sampling released last week, meanwhile, discovered the Democratic presidential nominee only 3 points ahead of Trump there.

Clinton edged out Trump 37 percent to 34 percent in that scenario, while Johnson registered at 15 percent. Another 8 percent backed Stein and 7 percent were undecided.

The Boston Globe said Tuesday the last time a Republican captured Maine was then-Vice President George H.W. Bush’s victory in 1988.

President Obama, in contrast, beat then-GOP presidential nominee Mitt Romney by 15 points during the 2012 election cycle.

Clinton leads Trump by about 2 points nationwide, according to the latest RealClearPolitics average of polls.
