Mr. Ciattarelli, a former state assemblyman, is running his third campaign for governor of New Jersey.
Jack Ciattarelli, a Republican endorsed last month by President Trump, easily won his party’s nomination on Tuesday to run for governor of New Jersey in November.
With about 20 percent of the estimated vote reported, Mr. Ciattarelli, a former state assemblyman competing for governor for the third time, beat his two main opponents, State Senator Jon M. Bramnick and Bill Spadea, a conservative radio host, by a convincing margin, according to The Associated Press.
Mr. Ciattarelli, 63, will now face the winner of the Democratic primary, Representative Mikie Sherrill.
Mr. Ciattarelli had been considered the front-runner for months, leading in most polls and in the race for campaign cash. Mr. Trump’s endorsement last month emphasized his goal of flipping New Jersey red after eight years of Democratic control.
After two previous campaigns for governor, Mr. Ciattarelli is a familiar name to many voters. He came within three percentage points in 2021 of unseating Gov. Philip D. Murphy, a Democrat. He did not concede defeat until 10 days after the polls closed — at a news conference where he also announced that he would try again in 2025.
Mr. Ciattarelli, a former accountant, has been running ever since.
His message about New Jersey’s lack of affordability resonated with Republican voters like Keyur Shah, an engineer from Paramus, N.J.
