Carly Fiorino may have just shot herself in the butt and may be the next person thrown under the political bus.

Carly Fiorina, the former Hewlett-Packard CEO turned top John McCain aide, said she doesn’t think Sarah Palin is qualified to run a major corporation. For that matter, Fiorina said, McCain, Obama and Biden aren’t capable of that kind of job either.

Fiorina was president of Hewlett-Packard until her high-profile ousting in 2006 after the company’s unfavorable performance.

“If John McCain’s top economic adviser doesn’t think he can run a corporation, how on Earth can he run the largest economy in the world in the midst of a financial crisis?” said Obama spokesman Tommy Vietor. “Apparently, even the people who run his campaign agree that the economy is an issue John McCain doesn’t understand as well as he should.” Watch Fiorina says Palin isn’t ready for big business »

Fiorina made similar comments earlier Thursday to a St. Louis, Missouri, radio station. She was asked if she thinks Palin is qualified to run a company like Hewlett-Packard.

“No, I don’t,” Fiorina answered. “But that’s not what she’s running for. Running a corporation is a different set of things.”
