Slowly, it appears as though the other Republican candidates in the presidential race are distancing themselves from supporting Donald Trump if he wins the nomination.

On NBC’s “Meet the Press” Sunday, Gov. John Kasich said that every day he reviews whether he could support Trump as the nominee.

“We're going to look at it every single day, and we'll see what happens. We've got a long way to go. And I don't want to project that he's going to be the nominee. I don't think he will be. And if he is ... I review it every day,” said Kasich.

Earlier this month, Kasich’s response to the question of supporting Trump was, “It’s tough, but he’s not going to be the nominee.”

And back in January his response was just, “I don’t believe he’ll be the nominee.”

But the tone of the Trump campaign clearly seems to be rubbing the Ohio governor the wrong way, especially the turn the it took this week as attention was focused on candidates' wives.

“Families have to be off limits," Kasich added Sunday. "I mean, you cannot get these attacks on families. And if this becomes the order of the day, what kind of people are we going to have in the future that are going to run for public office? There's got to be some rules, and there's got to be something that gets set there. Some decency.”

Kasich also, once again, resisted calls to get out of the race.

“If I'd have gotten out, Trump would be the nominee. He would have won Ohio. And frankly, we'll win some districts in Wisconsin. We will move to Pennsylvania, where I'm basically in a statistical tie with Trump,” he said.
