because the swift-vote thing is just the tip of the ice-burg. I assume that the swift-vet stuff was not coordinated, for the sake of this argument. The Bush campaign has much worse in store. And the sad thing for Kerry is that Bush will still manage to remain positive.
Coordination is very difficult to prove. It is kind of like proving collusion and price-fixing between gas stations on opposite corners of the same street. Remember when Kerry announced that he was "going dark" in August and admitted that it was a tacit message to others, i.e. DNC and 527s, to pick up the slack.
I think the Kerry campaign folks are really out of their league. They had to know this was coming. They know the hits on his past record are coming. If they continue to respond by acting like cry-babies, Kerry will look weak and ineffectual--not a place for a challenger to be. But hey, he served in Vietnam!
The grand strategy is unfolding. The rope-a-dope has begun. If Bush comes out of his convention with any kind of serious lead (i.e. five or more points), it will be lights out.
This is exactly where the Bushies want this race--Kerry defending Kerry.
