Ok.
Here's the thing.
There were issues before the Iraq War, and there will be after. Building up the political discussion around that issues alone is myopic. Some day (hopefully soon) we will leave Iraq, and if we build a coalition solely concerned about the Iraq War there will be no Democratic party when that day comes.
We have to talk about the minimum wage, healthcare, the Employee Free Choice Act that would allow workers the right to organize unions without being subject to dehumanizing NLRB elections when the company can break the law without fear of repercussions.
Someday Iraq will no longer be an issue. And we have to be prepared for that day. That's why people who focuse soley on that criteria for 2008 and beyond do the Democratic party a great disservice.
