You'll recall post of Jerome Corsi's were used. Not when they were made, when they'd be useful. Tony Snows were pulled, for good reason. When the Swift Boats are mentioned, there are often allusions to a right wing site. Edwards just had to fire two aids, and got some lousy press, over blog posts.
If I wanted to portray right wingers as homophobes or just general lunatics, there's plenty of fodder here.
