Charles Krauthammer told viewers Monday on “Special Report with Bret Baier” that he does not think the process of choosing delegates to the national convention “was designed to stop Donald Trump” from becoming the Republican presidential nominee.

Krauthammer, a syndicated columnist and Fox News contributor, responded to comments made by GOP front-runner Donald Trump over Texas Sen. Ted Cruz sweeping all of Colorado’s 34 delegates without any votes being cast by citizens in a traditional primary process.

“He doesn’t even have a chance to talk about his issues in New York,” he said. “He’s got to defend the ‘New York values’ stuff, which was an enormous mistake. It didn’t really help him in Iowa. He could’ve done it without that phrase. And now how does he defend it? He can’t. And I think because he is talking only about that, I think his numbers are going to stay very low here.”

Krauthammer’s comments come as the battleground for the 2016 presidential nomination has shifted to New York, Donald Trump’s home state. Former New York City Mayor Rudy Giuliani has said that he supports Trump.

“You’ve got people who are really holding their noses in support [of Trump] but with Giuliani, you get the sense that he is sort of sincere in this and he is relatively unreserved," he said. "Look, Giuliani is a folk hero in New York. He was, at the time a folk hero in the country. And I think that’s going to help soften the image for Trump."
