[11] On November 16, 2021, Laura Curran conceded the race for Nassau County Executive to Republican challenger Bruce Blakeman and left office on December 31, 2021.

[12][13] She attributed her loss to her name being on the same ballot as State Senator Todd Kaminsky, Democrat of Long Beach, for Nassau County District Attorney.
