Former vice president and presumptive nominee Joe Biden won the primary with more than 76% of the vote and all but two delegates, which went to senator Bernie Sanders, who missed the 15% threshold for statewide delegates with 13.6%.[2] Biden crossed the necessary majority of 1,991 delegates to officially win the Democratic nomination three days later during the vote count.[3]
Voting took place throughout the state from 6 a.m. until 6 p.m. local time. Candidates had to meet a threshold of 15% at the congressional district or statewide level to be considered viable. The 82 pledged delegates to the 2020 Democratic National Convention were allocated proportionally on the basis of the primary results. Of these, between 5 and 8 were allocated to each of the state's 9 congressional districts and another 9 were allocated to party leaders and elected officials (PLEO delegates), in addition to 18 at-large delegates.[5] Originally planned with 70 delegates, the final number included a 20% bonus of 12 additional delegates on the 46 district and 15 at-large delegates by the Democratic National Committee due to the original May date, which belonged to Stage III on the primary timetable.[6]
The state convention to designate the district-level national convention delegates had been planned for June 13 to June 17, but was replaced by an online vote in the same period. The district delegates then voted on the 18 at-large and 9 pledged PLEO delegates for the Democratic National Convention. The delegation also included 7 unpledged PLEO delegates: 5 members of the Democratic National Committee and 2 representatives from Congress.[5]
