Mother Jones released the full video of Republican presidential candidate Mitt Romney's speech to key donors on May 17. The video offers a rare unfiltered glimpse into how candidates interact with donors.

Joseph Tuman, a professor who focuses on political communication at San Francisco State University, said Romney would have never said some of the things in the video in public and that violates one of the key rules of campaigning.

"I'm just astonished how stupid this is," Tuman said. "This was foolish."
