Independent former Gov. Angus King has won the race to be next U.S. senator from Maine. Shortly after polls closed, ABC and NBC News called the race, saying King had beaten his opponents, Republican Charlie Summers and Democrat Cynthia Dill. He will replace retiring Sen. Olympia Snowe, a Republican. King has not said which party he will caucus with in Washington, but most observers believe he will join the Democrats as he supports President Obama.
King started the race as a heavy favorite, though Republican outside groups poured money into the race over the summer and fall in an attempt to hold the seat.
King will be one of two independents in the new U.S. Senate, along with Vermont's Bernie Sanders, who caucuses with the Democrats and was declared the winner in his reelection bid earlier Tuesday.
