“I think he’s very divisive and I do not believe he will last,” Kasich said when asked if he would support Trump if he wins the Republican primary.

Kasich pointed to Trump’s recent back and forth with TheNew York Times reporter Serge Kovaleski as a reason he won’t win the nomination. Trump has drawn criticism this week for appearing to mimic Kovaelski’s mannerisms, caused by a muscular disorder, which Kasich said Trump “absolutely mocked.”

“Somebody who divides this country, here in the 21st century, who’s calling names of women and Muslims and Hispanics and mocking reporters, and says, ‘I didn’t do it,’ but he did do it, it’s just not going to happen,” said Kasich.
