This post on MyDD sums up many of my feelings on the matter nicely.
Indeed, I continue to believe to this day that if John Kerry had had the guts to stand up and say "I supported this war, and I'm sick over it, because it was wrong and foolish" many people would have strongly identified with that. Polls showed throughout 2004 that many americans were coming to the same place.
Maybe he would have lost even worse, I don't know. But it would have been honest. A little of that would be nice for a change. The Democrats have got to figure out that they are never going to be able to out-lie, out-spin the Republicans. To quote a fairly hackneyed but nonetheless appropriate song, it's time to cut ties with all the lies we've been living in. And that goes for everything, across the board drug policy, the medical system, our idiotic foreign policy going back fifty years, all of it. We know all this stuff is based on lies.
Well, maybe Biden doesn't know it. But most of us do. What have we got to lose?
