You are on to something here. I do think Bill Burkett is the source but I do not think CBS would have taken his word for it. Someone higher up on the food chain would have had to say these are good documents. It would appear to me that the DNC has been putting leaking the documents to selected sources (not the media at first) to get them talking about Bush's record and then it went to CBS via someone very high in the DNC.
I have noted an absolute silence from the DNC on this subject, nor has the mainstream media sought to even ask the DNC about it.
I love the smell of burning liberal media in the morning. It smells like VICTORY
Like Rather's daughter. Until I see evidence otherwise, I'm speculating these documents were "reconstructed" for Michael Moore, possibly with Rather's daughter involved. Moore would believe anything negative about Bush so the discrepencies wouldn't have been noticed.
Moore's movie was a big hit, adding to the credibility of the charges. Then CBS heard about the documents and asked for them. Billy Bob Burkett was so thrilled to get a call from Dan that he forgot about the default font, and faxed them to CBS.
Burkett is a computer guy. If he had taken five minutes to change the font to Courier or Prestige, history would be different.
