Ted Stevens, the most senior Republican in the U.S. Senate, was convicted of all charges in a federal corruption case Monday, but he says he's not bowing out of the tight election race. Alan Simpson, a retired senator, said his famously cantankerous former colleague represents an earlier political era. "It was a time of lavish spending. It was a time of rewarding your friends," said Simpson. "It was like a new world caught up with him. It must have been frustrating."
