U.S. Rep. Mike Michaud maintains a comfortable lead in the race in Maine’s 2nd District, according to a new poll.

On Thursday, the Maine People’s Resource Center released the results from its latest survey of Maine voters, showing Michaud leading Republican Kevin Raye, 56 percent to 37 percent.

The results were similar to the center’s poll in April, which showed Michaud leading 53 percent to 37 percent.

Michaud campaign spokesman Dan Cashman acknowledged the positive news Thursday but said the five-term incumbent isn’t planning to coast on the latest results.

Raye’s campaign consultant, Kathie Summers-Grice, said the news is encouraging because the political affiliations of the people who were polled are out of step with the 2nd District, particularly with independent voters.

The Maine People’s Resource Center, which is affiliated with the liberal advocacy group the Maine People’s Alliance, polled 410 registered voters from Sept. 15 to Sept. 17. Forty-one percent were Democrats, 34 percent were Republicans and 24 percent were unenrolled or “other” voters.

The 2nd District’s 450,000 registered voters are 30 percent Democratic, 29 percent Republican and 40 percent unenrolled or other, according to the Secretary of State’s Office.
