The Associated Press called the race for Biden on Wednesday at 1:57 p.m. ET. Sanders was favored in forecasts in Maine heading into Super Tuesday, but Biden claimed victory in the Pine Tree State amid a surge in momentum heading into this week's contests.

Biden led the Vermont senator with 34.1 percent of the vote to Sanders’s 33 percent as of Wednesday afternoon. Sanders won the state with 64 percent in 2016.

The results mean that Biden has won 10 of the 14 states in which voters cast ballots on Super Tuesday, including major victories in Texas and Virginia.

Sanders won four states, including California, the top prize for delegates on Tuesday, though the exact delegate allocation from the state is not yet known.

Maine will award 24 pledged delegates in the Democratic nominating race.

Sanders’s state director, Benjamin Collings, told the Bangor Daily News that despite the senator's loss, the increased popularity of policy proposals such as a $15 minimum wage indicate he has “completely changed the Democratic party.”
