The Dems are preparing the postmortem on Kerry and laying the groundwork for Hillary 2008. If they honestly thought that Kerry would win we wouldn't be seeing Tony Coehlo, Pat Cadell and others in the party blasting his candidacy so openly to the media. They would be acting cocky and arrogant as they usually do knowing that victory was at hand.
You are right, and that's exactly what they were doing during their convention. What a difference 6 weeks makes. Another 6 and we'll be almost to Election Day.
