(CNN) —  

Former New York Mayor Rudy Giuliani is praising Donald Trump’s ability to draw audiences to the Republican presidential primaries.

“I think Donald has been refreshing,” Giuliani told CNN’s “New Day” Wednesday. “The debate you’re going to have next week is going to have three times the audience it would have had” without Trump.

Giuliani, who ran for president himself in 2008, said he “could” see Trump as president, but would not throw his support behind a specific candidate yet.
