Remember the Clinton Chronicles? How the media dismissed them as off the wall propaganda? Yet they were better supported by evidence than Moore's assertions.
The same will happen to any conservative film that attacks liberals in the future. No buzz, just dismissal.
That said, I wonder why there isn't a documentary exploring Kerry's Vietnam experience and his time afterward. So many unanswered questions, do much damning evidence.
At some point conservatives will realize that the media and the beltway establishment are friends of the state, not of conservative or libertarian principles. FNC and Rush Limbaugh are voices, but they exist at the pleasure of the permanent state apparatus. They give us the illusion of "freedom" when in fact they are just instruments of social control. There may come a time when we are presented with a real choice: stand up for our principles, or suck it up and avoid trouble. Which will we choose?
At that point, of course, it may not even look like a choice, if the media have been doing their jobs well.
