Well, we know Peter Osnos was involved -- I remember him from Washington Week in Review, never liked him, he's a genuine Clymer -- and that George Soros's money fuels the Org that Osnos works for.
I personally smell Sid the Squid in this.
Based on the few times I watched and grimaced at the pathetic performance of McClellan as press secretary, I would contend that he not only had a ghostwriter for his fictional piece of propaganda, but needed someone to read it to him.
