This post says Wesley Clark's political pros have undone pretty much all of the grassroots work done by the Draft Clark people. This seems like a classic "growing pains" or Clash of Paradigms issue. There is a Party establishment, who says there is the Right Way, the Wrong Way, and the Party Way. The tension between the old way (hierarchies, established lines of authority, etc.) and the adhocracies of the Netroots will continue, perhaps for another generation (depending quite a bit on how it works out in this election).
It's really hard to displace over a hundred years of social organization, even if you have really cool technology. I think that the "netroots" people will gain the upper hand only when they are able to gain critical mass, and to command large pools of capital. Dean's campaign may be on the way to doing just that.
