New York holds primaries in June 2021 for local partisan office, including New York city offices. The petitioning period for primary candidates runs from February 23 to April 1. According to this newspaper story, many potential candidates are asking Governor Andrew Cuomo for a reduction in petitioning requirements, because the health crisis isn’t over.

In 2019, the New York legislature moved the primaries for state and local office from September to June. New York wouldn’t be having this problem if the primary had remained in September.
