Republican Gubernatorial Candidates Compete in New Jersey Primary

As New Jersey’s Republican primary for governor approaches on June 10, 2025, the race has intensified among the party’s candidates vying to challenge the Democratic nominee in the November general election. The contest features a spectrum of Republican voices, each presenting distinct visions for the state’s future.

Jack Ciattarelli: The Trump-Endorsed Frontrunner

Jack Ciattarelli, a former state assemblyman and the GOP’s 2021 gubernatorial nominee, has emerged as the leading candidate in the Republican primary. Having narrowly lost to Governor Phil Murphy four years ago, Ciattarelli has since aligned himself closely with former President Donald Trump, securing Trump’s endorsement for his current campaign. This backing has bolstered his standing among Republican voters, with recent polls showing him leading the field with 44% support .

Ciattarelli’s platform emphasizes economic growth through tax reductions and deregulation. He has pledged to repeal New Jersey’s sanctuary state policies and appoint an attorney general who would not challenge federal immigration enforcement actions. Additionally, he proposes implementing a “reverse congestion pricing” toll on New York vehicles entering New Jersey, aiming to fund improvements to NJ Transit .

Bill Spadea: The Conservative Challenger

Bill Spadea, a former radio host and conservative activist, positions himself as a staunch advocate for right-wing policies. He has criticized Ciattarelli’s past moderate stances, branding him a “Republican In Name Only” (RINO), and argues that his own campaign represents true conservative values. Spadea’s platform includes opposition to COVID-19 mandates, support for parental rights in education, and a commitment to serving only one term to enact significant reforms.

Despite lacking Trump’s endorsement, Spadea has garnered support from the party’s right flank and has been endorsed by former state senator Edward Durr . Polls indicate Spadea holds approximately 18% support among Republican voters .

Jon Bramnick: The Moderate Voice

State Senator Jon Bramnick offers a centrist alternative within the Republican primary. A longtime legislator and former Assembly Minority Leader, Bramnick has been openly critical of Trump’s influence on the party. He advocates for bipartisan solutions, focusing on issues such as public safety, education, and government efficiency. Bramnick’s moderate stance appeals to voters seeking a departure from partisan extremes.

While his approach resonates with some segments of the electorate, Bramnick faces challenges in gaining traction within a primary electorate that has shown strong support for Trump-aligned candidates. Recent polling places him at around 8% support .

Other Republican Contenders

The Republican primary also includes candidates such as Mario Kranjac, former mayor of Englewood Cliffs, who campaigns on a platform of tax cuts, government reform, and strong support for Trump’s agenda . Additionally, Justin Barbera, a contractor and previous independent congressional candidate, is on the ballot, though he has not gained significant attention in the race .

Implications for the General Election

New Jersey’s gubernatorial race holds national significance as one of the few major elections in 2025. While the state has leaned Democratic in recent federal elections, Republicans see an opportunity to reclaim the governor’s office, especially amid concerns over taxes and public safety. The outcome of the Republican primary will set the stage for a competitive general election, with the GOP aiming to capitalize on voter dissatisfaction and the Democrats striving to maintain their hold on the state’s executive branch.

As the primary concludes, all eyes will turn to the general election campaign, where the Republican nominee will face off against the Democratic contender in a battle that could signal broader political trends heading into the 2026 midterm elections.
