Supported by Mr. Ciattarelli, a former state assemblyman, is running his third campaign for governor of New Jersey. By Tracey Tully and Alyce McFadden 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 90 percent of the estimated vote reported, Mr. Ciattarelli, a former state assemblyman competing for governor for the third time, was leading his two main opponents, State Senator Jon M. Bramnick and Bill Spadea, a conservative radio host, by a wide margin, according to The Associated Press. Mr. Ciattarelli, 63, will now face the winner of the Democratic primary, Representative Mikie Sherrill, 53. 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. “To our most well-known, part-time New Jersey resident who honored me with his endorsement and strong support: Thank you, President Donald J. Trump,” Mr. Ciattarelli said, eliciting raucous cheers from the assembled crowd in Holmdel, N.J. 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. Thank you for your patience while we verify access.
