John Kasich Vows to Campaign Until Convention If He Wins Ohio

"If I win Ohio, he’s not going to be the nominee,” Kasich said of Donald Trump.

“At the end of the day in all this, it is going to get down to a couple states, and Ohio is going to be absolutely critical,” Kasich said. “And we will go all out, and I will win Ohio.”

A victory in the Buckeye State would spread his message farther, Kasich said.

“When that happens, then people will begin to see more of who I am and what my message is and what our team is all about,” Kasich said, “and then we'll be able to compete in many other states."
