The 2020 Delaware Democratic presidential primary took place on July 7, 2020, alongside the New Jersey primary, as part of the Democratic Party primaries for the 2020 presidential election. It was originally going to take place on April 28, 2020, as one of several northeastern states in the "Acela primary", but was postponed due to the COVID-19 pandemic. The Delaware primary was a closed primary, with the state awarding 32 delegates to the 2020 Democratic National Convention, of which 21 were pledged delegates allocated on the basis of the primary results.
Former vice president and presumptive nominee Joe Biden, who represented the state in the senate for three and a half decades, swept all delegates in this primary, winning almost 90% of the vote. Senator Bernie Sanders, who still attempted to win delegates, took little more than 7% of the vote, with senator Elizabeth Warren, the only other withdrawn candidate, collecting the rest.

## Procedure

Delaware originally joined several northeastern states, which are connected by the Acela train system, as part of a regional cluster, the "Acela primary", in holding primaries on April 28, 2020. Governor John Carney postponed the primary first in March to June 2 and then in May to July 7. The Democratic National Committee granted a waiver for the late date outside of the window sanctioned by the party. New Jersey had moved its primary, which was originally planned on June 2, to the same date.
Voting took place throughout the state from 7:00 a.m. until 8:00 p.m. In the closed primary, candidates had to meet a threshold of 15 percent at the city and county or the statewide level in order to be considered viable. While Delaware consists of only one congressional district, the state party decided to subdivide its regional delegates between the 3 counties of the state and one city, being one of only two states in the Democratic Party to do so. The 21 pledged delegates to the 2020 Democratic National Convention were allocated proportionally on the basis of the results of the primary. Of these, between 2 and 8 were allocated to each of the state's 3 counties and the city of Wilmington and another 2 were allocated to party leaders and elected officials (PLEO delegates), in addition to 5 at-large delegates. Originally planned with 17 delegates, the final number included a 25% bonus of 4 additional delegates on the 11 county/city and 4 at-large delegates by the Democratic National Committee, 10% for the original April date, which belonged to Stage II on the primary timetable, and an additional 15% for the regional "Acela" cluster.
The delegate selection caucus, planned to be held on May 9, 2020, took place in Delaware on July 16, 2020, following representative district-level caucuses shortly before, where delegate selection caucus delegates had been chosen. The caucus voted on the county and city delegates, who then voted on the 5 at-large and 2 pledged PLEO delegates for the Democratic National Convention. The delegation also included 11 unpledged PLEO delegates: 6 members of the Democratic National Committee, all 3 members of Congress (both senators and one representative), the governor John Carney, and notably, former vice president Joe Biden.
In addition to delaying in-person voting from April 28, 2020, to June 2, 2020, to July 7, 2020, the requirements for using a mail-in absentee ballot had broadened to include voters who wished to follow public health guidelines for self-quarantine or social distancing even if they were experiencing no symptoms.

### Results by county

Favorite son Joe Biden overwhelmingly won all three counties; 73% of Sanders's votes came from New Castle County. Sanders failed to break the 15% threshold in any constituency, leading to a Biden sweep of delegates. Just over three percent of votes went to Elizabeth Warren, who had withdrawn from the race in March.

| Kent | 12,042 | 86.0% | 964 | 7.2% | 404 | 6.8% |
