Story highlights "It's mathematically impossible for John Kasich to become the Republican nominee," Cruz said

"Right now, Kasich's role is really being a spoiler. Kasich benefits Donald Trump," he said

Washington (CNN) Texas Sen. Ted Cruz said Wednesday that Ohio Gov. John Kasich needs to drop out of the Republican presidential race because "it's mathematically impossible" for him to become the nominee.

"You can't lose every state and expect to be the nominee," Cruz told CNN's Chris Cuomo on "New Day." "Right now, Kasich's role is really being a spoiler. Kasich benefits Donald Trump."

Kasich lost 27 states before winning his home state of Ohio, Cruz said. And the governor lost both Utah and Arizona Tuesday.

Cruz argued that Kasich, who trails both Trump and Cruz in the delegate race, would need to win "more than 100% of the remaining delegates" in order reach the 1,237 required to secure the nomination. As of Wednesday, Trump leads with 741, Cruz has 461 and Kasich has 145.

"Under the rules, he won't even be on the ballot. The (Republican National Committee) rules provide that to be on the ballot you have to have won 8 states. There are only two people who meet the threshold -- Donald Trump and me," Cruz said. "Kasich cannot even be voted on at the convention."
