Clips from the show to be aired Sunday show Rendell arguing that gambling addicts already have available casinos. He said that now, at least, Pennsylvania will benefit instead of Atlantic City, N.J.

"You're simpletons, you're idiots if you don't get that, Rendell said.
Rendell is in the last days of his second term as governor. He served as Philadelphia district attorney and mayor.
The "60 Minutes" segment, "The Big Gamble," describes states' increasing use of casinos for revenue, to the point that there are now more slot machines than ATMs in the United States.
