Camden County Republican Chairman Thomas Crone lost his bid for re-election to a second term, losing to former Haddon Heights Board of Education President Kimberley Stuart.
Stuart won, 92-61, a 60%-40% margin.
Winslow Councilman Brandon Gilkes was elected vice chair, along with Waterford Councilwoman Stephanie Jones Freitag as secretary and John Downham of Haddon Heights as treasurer.
Stuart, a former assistant counsel to two New Jersey governors, Christine Todd Whitman and Donald DiFrancesco, served four terms on the school board and is a former municipal prosecutor.
Crone is the fourth Republican county chair to lose this year, following Jacci Vigilante in Gloucester, Tim Howes in Somerset, and Glenn Mortimer in Union.
In Bergen County, former Hasbrouck Heights Mayor Jack DeLorenzo was elected GOP county chairman without opposition. Jack Zisa, who decided to step down after six years, had backed DeLorenzo as his successor.
Burlington County Republican Chairman Sean Earlen was re-elected without opposition.
Crone was elected in 2022 defeating Nicole Nance by a vote of 59-42. He replaced Richard Ambrosino, who did not seek re-election after five years as county chairman.
Ambrosino won a February 2017 special election for county chairman to replace Thomas Booth, Jr. Booth had resigned to become a Superior Court Judge.
