The 2025 Nassau County Executive election will be held on November 4, 2025, to select the County Executive of Nassau County, New York. Incumbent Republican County Executive Bruce Blakeman, first elected in 2021, is seeking re-election to a second term. He was nominated by the Republican and Conservative parties, and his challenger in the general election is County Legislator Seth Koslow, who was nominated by the Democratic and Moderate parties.[1]
Koslow announced that he would challenge Blakeman on January 8, 2025, with endorsements from former County Executive Laura Curran, whom Blakeman defeated in 2021, and Congressman Tom Suozzi, who was County Executive from 2002 to 2009.[5] Though Blakeman was at a financial disadvantage in his 2021 campaign,[6] he outraised Koslow significantly in the first half of the year, raising $2 million to Koslow's $430,000 through July 15.[7]
Despite President Donald Trump narrowly winning Nassau County in the 2024 presidential election,[5] Koslow has attacked Blakeman over the effects of Trump's tariffs in the county, which Blakeman has defended,[8] and over the effects of the Big Beautiful Bill on the county.[9]
