2021 New York City Democratic mayoral primary

The Democratic Party primary for the 2021 New York City mayoral election took place on June 22, 2021. Brooklyn Borough President Eric Adams defeated 12 other candidates, including Kathryn Garcia, Maya Wiley and Andrew Yang. Adams went on to defeat Republican Curtis Sliwa and other candidates in the November 2, 2021 general election.

Background
In 2019, New York City voters passed Ballot Question #1 to amend the City Charter to "give voters the choice of ranking up to five candidates in primary and special elections for mayor, public advocate, comptroller, borough president, and city council beginning in January 2021". The first election in the city to use ranked-choice voting was in the 24th council district in Queens, which took place on February 2, 2021, though the first ranked-choice election with multiple rounds was held in the 31st council district in Queens on February 23. The 2021 mayoral primaries were the first New York City mayoral election primaries to use ranked-choice voting.

In 2019, journalists and political commentators predicted several potential candidates, including Brooklyn Borough President Eric Adams, Bronx Borough President Rubén Díaz Jr., NYC Council Speaker Corey Johnson, NYC Comptroller Scott Stringer, and NYC Public Advocate Jumaane Williams. All of the preceding candidates ended up joining the mayoral race with the exception of Williams, who instead decided to run for re-election as Public Advocate. Additionally, Díaz Jr. and Johnson dropped out before the primary election, with Johnson instead deciding to run for Comptroller.

Early months
Polling in late January and early February showed businessman Andrew Yang as the frontrunner, with Adams in second and Stringer in third place. As of January 20, 2021, of the major declared candidates, New York City councilmember Carlos Menchaca and former Commissioner of the NYC Dept. of Veterans' Services Loree Sutton were considered the weakest candidates and most likely to drop out, as both of them posted very poor fundraising numbers. Sutton withdrew from the race on March 10, 2021 and Menchaca withdrew on March 24, 2021. By the middle of March, three candidates, Stringer, Dianne Morales, and Maya Wiley, were widely considered to be the chief competitors for the progressive vote. In April, Yang faced criticism when he appeared on a video by Comedian Lawrence Reese in which he appeared to laugh when Reese asked him if he "choked bitches".

Stringer sexual assault allegations
In April, Stringer, who was generally polling in third-place, was accused of sexual abuse by Jean Kim, who claimed that Stringer had forcibly kissed and groped her when she worked on his 2001 campaign for Public Advocate. Fellow candidates Morales, Adams, Yang, and Raymond McGuire condemned the acts in the allegation; while candidates Wiley, Kathryn Garcia, and Shaun Donovan called for him to drop out. Stringer denied the allegations, claiming that the relationship had been consensual. In June, a second woman accused him of sexual misconduct in 1992.

Debates
The first debate in the Democratic primary was sponsored by the Brooklyn Democratic Party and held on January 31, 2021. Eight candidates participated: Adams, former director of the US Office of Management and Budget Shaun Donovan, former commissioner of the NYC Dept. of Sanitation Kathryn Garcia, businessman Raymond McGuire, Stringer, Sutton, former counsel to Bill de Blasio Maya Wiley, and Yang. Former non-profit CEO Dianne Morales boycotted the debate following comments perceived as sinophobic by a former Brooklyn Democratic Party official.

The second debate took place on May 13, 2021. It was organized by the New York City Campaign Finance Board (CFB) and sponsored by NY1. Eight candidates met the CFB's qualifications to participate in the debate. Those who participated were Adams, Donovan, Garcia, McGuire, Morales, Stringer, Wiley, and Yang.

The third debate was held on June 2, 2021. It was organized by the CFB and sponsored by ABC 7. Eight candidates met the CFB's qualifications to participate in the debate. Those who participated were Adams, Donovan, Garcia, McGuire, Morales, Stringer, Wiley, and Yang.

The fourth debate was held on June 10, 2021, and sponsored by CBS 2. Five candidates participated: Adams, Garcia, Stringer, Wiley, and Yang. Adams initially announced that he would skip the debate but later opted to attend.

The fifth and final debate of the Democratic primary took place on June 16, 2021. It was organized by the CFB and was sponsored by NBC 4. Eight candidates met the CFB's qualifications and were required to participate: Adams, Donovan, Garcia, McGuire, Morales, Stringer, Wiley, and Yang.

Closing weeks
On May 5, 2021, Politico reported that a recent poll found that Eric Adams was leading the Democratic primary contest; this marked the first time since January that any Democratic candidate other than Yang had led in a public poll. On June 7, Spectrum News reported that Adams had maintained a lead in the Democratic primary.

In early May, Donovan and McGuire were characterized as being out of touch with everyday New Yorkers for greatly underestimating the median cost of a home in Brooklyn. In late May, Yang, who lives in Hell's Kitchen, faced some ridicule for answering that Times Square was his favorite subway station; the response was seen as akin to that of a tourist. Yang was also criticized as being out of touch when he appeared before the Stonewall Democrats of New York City for an endorsement screening, in which he appeared to point to his gay colleagues and supporter on the basis of their gender and sexuality rather than why they were important to him. Later in May, Morales's campaign lost three senior staff members amid allegations of a poor workplace culture and union-busting. Morales's campaign lost some endorsements and support.

In June, due to ongoing rumors that he lived in New Jersey, Eric Adams invited reporters to Bedford-Stuyvesant to tour an apartment that he claimed was his residence. Yang asked his supporters to rank Garcia second, though she did not make a similar request of hers. Adams claimed the alliance was an attempt to disenfranchise Black and Latino voters, a claim that Garcia and Yang disputed, with rivals and officials such as Wiley and Williams claiming that Adams was using race in order to undermine confidence in the election.

Results
On June 29, the New York City Board of Elections became aware of a discrepancy in the unofficial primary results and subsequently posted in a tweet that both test and election night results were tallied together in an error, adding approximately 135,000 additional votes.

On July 6, after new vote tallies were released, the Associated Press declared Eric Adams to be the winner of the primary. The Guardian stated that Adams had prevailed "after appealing to the political center and promising to strike the right balance between fighting crime and ending racial injustice in policing". An earlier report from The New York Times asserted that Adams had run as a "working-class underdog" and had "hammered away at the message that he was the only candidate who could tackle both crime and police reform". The Associated Press later added that Adams had made "his rejection of left-leaning activists’ calls to defund the police" a "centerpiece of his campaign".

Adams was heavily favored to prevail in the general election.
