On March 28, New York State elections officials moved the primary date to June 23 due to concerns over the COVID-19 pandemic.

Donald Trump was the only Republican candidate to submit the required number of names of his 162 total delegates, both the 94 primary ones and the alternates.

Among Trump's major challengers, Bill Weld only submitted about half of his required delegates, and neither Rocky De La Fuente nor Joe Walsh sent in any names at all.

Bill de Blasio as well dropped out on September 20, 2019, after failing to qualify for the fourth Democratic debate.

[16] Several prominent Democrats, including Senators Bernie Sanders, Elizabeth Warren and Kirsten Gillibrand, U.S. Representative Alexandria Ocasio-Cortez, and Senate Minority Leader Chuck Schumer encouraged voting for Biden and Harris on the WFP line, in order for the party to keep ballot access.

Future of Freedom Foundation Founder Jacob Hornberger was the sole candidate to qualify for the New York primary ballot.

[51] New York continued its streak as a solidly blue state, with Biden winning 60.87% of the vote to Trump's 37.74%, a Democratic victory margin of 23.13%.

New York's inexperience processing a large number of mail ballots, having only legalized no-excuse absentee voting in 2019,[5][52] led to weekslong delays in counting them.

[54] New York failed to meet its November 28 deadline to certify the election, with hundreds of thousands of votes still uncounted.

The delay in the counting of mail-in ballots wrongly made it seem at first that Biden had underperformed Hillary Clinton in 2016, a phenomenon referred to as a "red mirage.

Donald Trump is the first Republican to receive 3 million or more raw votes in New York since George H. W. Bush in 1988.

[63] New York was one of five states in the nation in which Biden's victory margin was larger than 1 million raw votes, the others being California, Maryland, Massachusetts and Illinois.
