Former vice president and presumptive nominee Joe Biden won the primary with roughly 73% of the vote and won 30 delegates, helping him cross the necessary majority of 1,991 delegates and officially win the Democratic nomination three days later during the vote count,[1] while senator Bernie Sanders, who had suspended his campaign two months earlier, narrowly passed the threshold of 15% and received 4 delegates and senator Elizabeth Warren, also withdrawn, received most of the remaining votes with around 6%.

New Mexico was one of seven states and the District of Columbia that voted on June 2, 2020, in the Democratic primaries, along with Indiana, Maryland, Montana, Pennsylvania, Rhode Island and South Dakota.

In the closed primary, candidates had to meet a threshold of 15% at the congressional district or statewide level in order to be considered viable.

The 34 pledged delegates to the 2020 Democratic National Convention were allocated proportionally on the basis of the primary results.

The delegation also included 12 unpledged PLEO delegates: 5 members of the Democratic National Committee, 5 members of Congress (both senators and all 3 representatives), the governor Michelle Lujan Grisham, and former DNC chair Fred R.
