If Clear Channel collapses, GWB may lose his main attack dog in world politics. The gem of Clear Channel, of course, is none other than Rush Limbaugh. Limbaugh often talks about the "drive by" media and character assasination, but none is better at it than Limbaugh, and his "sic 'em" master, Clear Channel Communications. If Clear Channel does collapse, it could be a blessing in disguise.
