I really don't think there's much reason to be doubtful of DBB having a source. Quality of source, and certainly bias of source, flame away. But between the Pace call, naming the exact day and candidates of certain candidates, and being the only one to say that George would announce a restructuring at the PC, means he has a real source. Some have speculated its close to Ted, which sounds like a reasonable assumption. But if it's not Ted himself then there's gonna be an opportunity to have bad, biased, or incomplete info from time to time. Still for rumor-mill blogging and not traditional, well vetted, journalism standards, it seems pretty good.
