King announces recent endorsements; polls released; Chamber files spending reports

It’s been a busy day tracking developments in the Maine Senate race.

Independent former Gov. Angus King announced endorsements from a number of organizations in Portland, two independent polls were released and showed his lead in the campaign for Maine’s open U.S. Senate seat shrinking, and the U.S. Chamber of Commerce filed reports with the Federal Election Commission showing it’s spending $439,000 on its latest ad attacking King.

King announced endorsements at his Portland office from the Maine Credit Union League, the New England Regional Council of Carpenters, American Nurses Association – Maine, the National Wildlife Federation, the Sierra Club, and the Professional Firefighters of Maine.

Mark Erlich of the New England Regional Council of Carpenters said, “At a time of gridlock in our nation’s capital…King will stand out as a voice of reason.”

One of King’s endorsements, from the Sierra Club, sparked some frustrated comments earlier this week from Democrat Cynthia Dill, whose positions align more closely with the organization’s. And some of the organizations that announced their backing for King on Wednesday have traditionally backed Democrats, further indicating that King is attracting more support from Democrats than he is from Republicans.
