TRENTON -- Just back from campaigning for Republican presidential front-runner Donald Trump in Indianapolis on Wednesday, Gov. Chris Christie insisted the mogul will clinch the Republican Party's nomination with the help of the New Jersey primary.

Appearing on his monthly call-in radio show "Ask the Governor" on NJ 101.5-FM on Wednesday night, Christie was adamant that "New Jersey will clinch the nomination for Donald Trump on June 7."

"Take it to the bank," he said.

The tycoon, who owns three New Jersey golf courses, needs to have secured 1,237 bound, declared delegates after the last Republican primary ends on June 7 to be the party's presumptive nominee. California, New Mexico, Montana and South Dakota all hold their primaries on the same day as the Garden State.

"Just like we put Mitt Romney over the top at the (Republican) convention four years ago, during the voting on the floor? We will, as a practical matter, put Donald Trump over the top on June 7th here in New Jersey," the governor predicted, adding, "He will win all the delegates here."

Trump currently has 845 delegates. U.S. Sen. Ted Cruz of Texas has 559, while Ohio Gov. John Kasich has 148.

In a new Rutgers Eagleton poll released on April 18, Trump was named by 52 percent of registered Republican voters as their first choice. Kasich was a distant second in the Garden State, with 24 percent. Cruz came in third at 18 percent.

New Jersey's GOP primary awards its 51 delegates on a winner-take-all basis. That means that whichever candidate wins the statewide vote gets all the votes on the first ballot at the party's national convention in Cleveland this July, regardless of to whom those delegates might be previously pledged.
