Former US Vice President Joe Biden won Hawaii's Democratic presidential primary on Saturday, in the latest victory on his march toward the party's 2020 nomination.

Biden defeated Senator Bernie Sanders (I-VT), who dropped out of the race last month but whose name was still on the ballot, by a comfortable margin, earning 63 percent of the vote to Sanders' 37 percent.

Biden won 16 of the state's delegates and Sanders earned eight, according to The Hill.

The 16 delegates now give the former Vice President a total of 1,566 to the Democratic Party's convention. Biden is projected to reach 1,991 delegates, the threshold needed to win the nomination, by June.

Hawaii's primary was conducted on Saturday following a weeks-long delay because of the coronavirus outbreak. The party-run election was held entirely by mail, with just more than 35,000 voters casting ballots.

Since Sanders dropped out of the race, Biden has received the backing of several high-ranking Democrats, including former President Barack Obama and former Secretary of State Hillary Clinton.

Biden has also been endorsed by Sanders himself and by Massachusetts Senator Elizabeth Warren, who had also sought the Democratic nomination but dropped out.
