BradBlog.com has put together a great video, showing the standard FOX "News" tactic of shifting the topic away from news that is critical of Republican strategies. It's rather long, but very instructive. Rather than talk about any flaws that "The Petraeus Report" may have had, they shift the focus to a MoveOn.org ad that points out those flaws. And notice, you see very little actual discussion about what was so wrong, only that they WERE wrong, and MoveOn is evil. Or something.
As I said, it's long, but is a very good clip.
