Charles Krauthammer appeared on "The O'Reilly Factor" tonight to react to the second GOP debate and how the 11 candidates in the main event fared.

Krauthammer said that he believes Carly Fiorina won the debate, with Marco Rubio coming in a close second and Chris Christie coming in third.

He gave Fiorina an "A-" and said that she had several strong moments, particularly when she responded to Donald Trump's "Look at that face!" insult.

Krauthammer said that Rubio didn't have as many memorable moments, but he had a consistently high performance across the board.

He said that Christie also had a good performance, showing himself to be strong and controlled with a bit of humor.

As for the losers, Krauthammer said that Donald Trump, Ben Carson, Mike Huckabee and John Kasich didn't fare as well. 

Watch Krauthammer's full analysis above.
