East Windsor Mayor Janice S. Mironov will not seek a fifth two-year term as Mercer County Democratic Chair, ending an eight-year tenure as leader of one of the state’s most successful county political organizations.
The leading candidate to succeed her is Jennifer Keyes-Maloney, a Ewing councilwoman and longtime Democratic stalwart.
Under Mironov’s tenure, no Republican currently holds a federal, state, county or municipal office elected in a partisan election; only Hudson County can claim a similar success. Democrats flipped the Hamilton mayor’s office in 2019 when Jeff Martin ousted Republican Kelly Yaede, and captured GOP council seats in Hamilton, Hightstown, Hopewell Borough and Hopewell Township.
In the 16th legislative district, Mironov helped Andrew Zwicker (D-South Brunswick) secure the Democratic nomination for State Senate. Zwicker flipped the seat held by retiring Republican Christopher Bateman (R-Branchburg).
County conventions stopped being automatic wins for incumbents. Mironov’s neutrality in the 2023 race for County Executive between five-term incumbent Brian Hughes and Assemblyman Dan Benson (D-Hamilton) shouldn’t be overinterpreted, however. Six councilmembers and the township’s Democratic municipal vice-chair have all gotten behind Benson, something they would not have done without Mironov’s approval.
“Janice has been a trusted partner for many years, and I’m grateful for everything she’s done to unify and strengthen Mercer Democrats during her time as County Chair,” said Benson. “I know that we’ll continue to work closely with Mayor Mironov on behalf of our residents, and that leaders across Mercer County and beyond will continue to depend on her mentorship and advice as we move our Party forward.”
Mironov was an early supporter of Mikie Sherrill’s campaign for the Democratic gubernatorial nomination in 2025; in the primary, Mercer delivered a significant 37% victory for Sherrill – a margin of over 15 points in a six-candidate race. Sherrill won 71% of the vote in Mercer in the general election. In 2021, Mercer delivered 65% for Gov. Phil Murphy; his margin of over 30,000 votes was about one-third of his statewide margin.
Sherrill praised Mironov for her service and leadership.
“Chairwoman Mironov was an early partner and trusted advisor, sharing her expertise in local government to help shape my campaign’s vision for lowering costs, addressing the housing crisis, and strengthening municipalities,” Sherrill said. “As one of the few women serving as county chair, she has repeatedly demonstrated the importance of having women at the table to shape effective policies that drive meaningful change for working people. I’m grateful for her leadership and all her work to elect strong Democrats who share this vision.”
Mironov will continue as the mayor of East Windsor, a post she has held for nearly 30 years.
“I’m honored by the trust that Mercer County Democrats have placed in my leadership and proud that together we’ve put Mercer County on the map,” said Mironov. “My primary interest has always been government delivering to folks and legislative policy engagement – all of which I continue to enjoy as Mayor of East Windsor and my broader roles statewide. I’m not going anywhere, and I will continue to play a major role in the Democratic Party and collaborate with the Sherrill Administration to advance affordability measures and improve coordination with local government.”
Mironov became county chair in 2018 after Verlina Reynolds-Jackson (D-Trenton) resigned following her election to the State Assembly.
Mironov also focused on expanding the party’s big tent. During her tenure, the Mercer County Young Democrats and Mercer County Latino Caucus were revitalized, and the Progressive Caucus became an official part of the county organization. At the same time, she strengthened the committee’s fundraising and organizational operations, leaving the Mercer County Democratic Committee with its deepest resources and strongest infrastructure in decades.
“I’ve been truly fortunate to be a part of Mayor Mironov’s team and witness the impact of her leadership close-up,” said County Commissioner Sam Frisby, the MCDC Vice-Chair. “Her ability to tune out distractions and to work through complex issues with a relentless focus is one of the things that makes her a tremendous leader. Because of her dedication and hard work, our party is much stronger than it was eight years ago.”
