Republican Presidential Debate: The Best Zingers From The Second Republican Debate

From Donald Trump to Carly Fiorina, the best lines of the GOP debate.

— -- Candidates rolled their eyes and threw plenty of punches on the GOP debate stage tonight.

Paul shot back, calling Trump "sophomoric."

“Do we want someone like that to be negotiating with Iran?," he asked. "I think really there is a sophomoric quality that is entertaining about Mr. Trump...Would we not all be worried to have someone like that in charge of the nuclear arsenal?”

Trump shot back with another zinger.

“I never attacked him on his looks and believe me, there is plenty of subject matter there," he said. "That I can tell you."

Fiorina also took on Trump and his comments about her face in a recent Rolling Stone interview.

"Women all over this country heard very clearly what Mr. Trump said," Fiorina responded to some of the loudest applause of the night.

Fiorina and Trump weren't the only candidates to get a strong response from the audience. Laughter erupted after the famous neurosurgeon Dr. Ben Carson turned one of Trump's criticisms of him around. Carson called Trump an "an O.K. doctor" after he explained his position on vaccines.
