[Caller:] "The Daily Show" seemingly has patented a technique of finding old video clips of politicians directly contradicting themselves and highlighting those contradictions. It's especially illuminating to see the words coming out of their mouths -- that's harder to refute than a printed story. Why don't we see this more on actual news shows? Isn't that a good way of finding truth in a world of spin -- or at least of pointing directly at the spin and making it more obvious?
Howard Kurtz: We are starting to see more of that on actual news shows, which are taking a page from the "Daily Show" playbook. Jon Stewart didn't invent the technique, but he's used it to great effect. It helps to have a small army of TiVo researchers, as he does.
