WASHINGTON - Independent Senator-elect Angus King of Maine said Wednesday he has decided to caucus with Democrats, which will add to the party's voting edge.
His decision ends months of speculation about which party he would align with.
The former Maine governor was elected last week to replace retiring Republican Sen. Olympia Snowe, a prominent centrist who complained about Washington's partisan gridlock in stepping down. GOP and conservative super PACs spent millions of dollars to attack King during the campaign for Snowe's seat.
With King joining their caucus, Democrats will have a 55 to 45 edge in the Senate.
King said that caucusing with Democrats will still allow him to take independent positions on issues.
"I have decided to affiliate with the Democratic Caucus because doing so will allow me to take independent positions on issues as they arise and at the same time be an effective representative for the people of Maine," King said.
Senate Democratic Leader Harry Reid of Nevada welcomed King to the caucus.
"I'm confident Senator King with be a bridge to working with Republicans," Reid said.
