Bush's beef about news from Iraq is a variation on the famous complaint that the media never report about all the planes that land safely. And it's true: Many American soldiers have not been killed since the war officially ended. You rarely read stories about all the electricity that works, or the many Iraqis who aren't shouting anti-American slogans. For that matter, what about all the countries we haven't invaded and occupied in the past year? And what about the unreported fact that Saddam Hussein has been removed from power? Well, maybe that isn't actually unreported. But an unfilterish media would surely report it again and again in every story every day, in case people forgot.
Every president complains that the media are blocking his message, and the media complain that every administration wants to manage the news. It's not only presidents. Everyone who has something to say in our media-saturated culture (and who doesn't?) longs for ways to get that message out unmediated by someone else. In this media cacophony, the president probably has more ability to deliver his message without a filter than anyone else on earth. Anything the president says is automatically news. If he wants to commandeer all the TV networks for a speech in prime time, he can usually do it. The president can even hold a press conference, although this president rarely bothers.
