Though Christie isn’t the only man running for the Republican nomination, he’s quickly cemented his status as the frontrunner since entering the race earlier this month, and has picked up the backing of hundreds of Republican state officials. Last week, he secured the endorsement of New Jersey’s former governor Tom Kean.
With Corzine looking vulnerable - he trailed Christie by six points in a recent Quinnipiac poll - prominent national Republicans like Giuliani are expected to lend their star power to the race.
Giuliani said his fellow former prosecutor is “a decisive leader who knows how to make the tough decisions.” He also praised Christie’s commitment to urban revitalization, a central plank of his gubernatorial bid.
“I am humbled to have the support of Mayor Giuliani, whose strong leadership made New York City a better place and positively affected the lives of so many New Jerseyans,” Christie said.
Giuliani has also raised money for Virginia gubernatorial candidate Bob McDonnell, who, like Christie, is aiming to take back the office from Democrats this fall.
