Over 58 percent of the nearly 30,000 votes cast went to Sanders, while former Vice President Joe Biden won 23 percent of the votes.
Sanders was awarded nine of the 13 delegates at stake in the primary and Biden received the other four, The Hill reported.
Sanders walked away with 69 percent of the vote in the primary four years ago, while former Secretary of State Hillary Clinton won 30 percent.
Biden is widely seen as the inevitable 2020 Democratic nominee given his massive delegate lead over Sanders.
However, it could still take a number of contests for the former vice president to win enough delegates to officially win the nomination.
The coronavirus outbreak has caused a number of states, including Ohio, Georgia, Louisiana, Connecticut and Kentucky, to postpone their primaries.
Biden’s campaign has since gone virtual and has taken to tele-town halls, online fundraising events, and daily briefings on the crisis surrounding the virus.
Sanders’s campaign has said he will reassess his campaign but has yet to drop out of the race.
