Sen. Rand Paul had his best night in Tuesday’s Republican primary debate, but it won’t be enough to alter his fortunes, Charles Krauthammer said tonight on Fox News’s Special Report.

“I give him points for courage and candor,” Krauthammer said. “I mean his sort of isolationism is not a popular strain, but he went with it.”

Nonetheless, “I don’t think anybody really changes his or her fortunes.”

Instead, he predicted how things will shake out from here: “If you look at the stage, you saw the two wings, you had Rand Paul and you had Kasich, who you could just see falling through a trap door. And then you have Carly Fiorina and Jeb, who I think are also rather tentative.”

“And then you look in the center and you saw the final four,” he continued. Meaning, Donald Trump, Ben Carson, Ted Cruz, and Marco Rubio.
