Pain at the Pump: What's behind the High Gas Prices?

Republicans are blaming the President, and he's announcing new energy strategies, as gasoline is up to $4 a gallon in parts of the country. What are the real reasons for the increase? How long is it likely to last? We talk with Daniel Yergin and others. Also, NATO's burning of Korans sparks riots in Afghanistan, and Rick Santorum is being asked about his statement in 2008 that, "Satan has his sights on the United States of America." Was it aimed at then candidate Barack Obama? Should all candidates face questions about their religion?
