I'd like to think the cancelling of Keith Olbermann and now Glenn Beck's programs are part of an effort to tone down the political bantering on both sides. After the shooting in Arizona I think networks like msnbc came under fire, and it was only a matter of time before the Right had to own up to their part in the increasing hostile political climate that cable news has helped foster the past years. That and the fact that Glen Beck types were costing Republicans any chance they had at winning back the Presidency amongst more moderate and independent voters.
