The $21 million John McCain spent on this reelection is more than he's spent on all of his senate races combined since he was first elected in 1986. It still doesn't come close to the $50 million spent by former health care executive Rick Scott in his successful bid to beat Florida Attorney General Bill McCullom for that state's GOP gubernatorial nomination. We look at these and other primary results from Florida, Arizona, and a nail-biter in Alaska with TIME Magazine's national political correspondent Jay Newton-Small.

The statistics of New Orleans tell the story of a city that has changed remarkably since Katrina devastated the Gulf region five years ago. The hurricane damaged or destroyed 180,000 homes, and of the people who left the city after Katrina, about 100,000 of them haven't returned. The demographics and economics of the city have changed, but what about the people? Bruce Nolan of the Times-Picayune says today "New Orleans is, physically and psychologically, like a patient recovering from a whole-body burn." We speak with Nolan and Bill Quigley, co-author of the Katrina Pain Index and legal director of the Center for Constitutional Rights.

33 miners in Chile remained trapped nearly a half mile below ground. They've been there for three weeks and officials say it could take months to rescue them. We'll speak with Gideon Long of the BBC who is at the scene.

We rebroadcast our conversation with David Kessler, former commissioner of the FDA. Kessler did some dumpster diving, read the fine print, and studied the research about what goes into the food we eat. His book, just out in paperback, is "The End of Overeating: Taking Control of the Insatiable American Appetite."

That's the suggestion Howard Mansfield makes in his new book, "Turn & Jump: How Time & Place Fell Apart." He reminds us that time and place used to be inseparable, that local time was sun time. The seasons provided the clock. That changed when the railroads standardized time. Mansfield believes there was a cost to that change, and he joins us to talk about changes in time.
