Arianna: Change Requires Continued Participation

Arianna appeared on CNN's "The Situation Room" Tuesday evening to discuss President Barack Obama's newly-published Rolling Stone interview, in which Obama upbraids the Democratic base's lack of enthusiasm, and the threat of a "Third World America" for the middle class given the sputtering economy.

"The President is right in many ways," Arianna told host Wolf Blitzer. "The anger and the frustration, the disappointment, are legitimate. But ... people need to keep participating to bring about change. It's never easy."

And there are a lot of changes to make, she said, if America is to reverse the damage done to the middle class in recent decades.

"I think the anger is at what's happened to the middle class over the last 30 years," she said. "I think that we are in for a series of 'throw the bums out.'"
