Former Vice President Joe Biden is expected to win Tuesday’s Democratic presidential primary in Idaho.

With 96 percent of precincts reporting, Biden is leading with 48.4 percent of the vote while Sen. Bernie Sanders has 42.5 percent, leading the Associated Press to call the race for him.

The state has 20 delegates up for grabs in its first-ever primary.

In 2016, Idaho’s Democrats selected Sanders as their preferred candidate over Hillary Clinton in the state’s caucus.

Idaho marked Sanders’ fourth loss of the night, shrinking his chances of becoming the Democrat nominee for president in 2020.

The Vermont Senator also lost Michigan, Arkansas, and Mississippi to Biden, with Washington state and North Dakota too close to call at the time of publication.
