“A movement of maybe 10 percentage points one way or another could decide whether it's going to be open convention or whether Donald Trump can close it out on the first ballot,” says Edward Cox.

The chairman of New York Republican State Committee went On the Record tonight to sound off on the state’s upcoming critical primary, where Donald Trump has been enjoying a lead in the polls.

With its 95 delegates, New York has “more than any state going forward except for California,” Cox told Greta. “So it's a big treasure trove of delegates.”

“The greatest political show on earth has landed right here playing almost exclusively in New York state and it’s very exciting,” he said.

“This is going to a decisive primary and the grassroots are going to get to decide who the nominee is going to be and who the next president of the United States may be.”
