Despite OC's reputation as a conservative bastion, it has two die-hard progressives: Mike Kaspar and Nathan Callahan, who created Weekly Signals on KUCI to entertain and educate their listeners about the latest nonfiction books. How successful is the Tuesday-morning show? It routinely offers interviews with the likes of Sidney Blumenthal, Vincent Bugliosi, Andrei Codrescu, John Dean, Karen Finley, Daniel Ellsberg, Seymour Hersh, Susan Jacoby, Michael Parenti, Kevin Phillips and David A. Vise, to name a few. The pair's May interview with Peter T. Leeson, author of The Invisible Hook: The Hidden Economics of Pirates, revealed that pirates were simply businessmen who used outrageous costumes and dark symbolism to frighten targeted ships into surrendering peacefully. Investigative journalist Russ Baker, author of Family Secrets: The Bush Dynasty, the Powerful Forces That Put It In the White House, and What Their Influence Means for America, shared the reasons (espionage alert!) why the Bush family might have surpassed the Kennedys in raw power. Tom Vanderbilt, author of Traffic: Why We Drive the Way We Do, explained the psychology of what drives Southern Californians crazy. It's provocative listening that will guide your next Borders purchase.
