Also, I don't really think that Clark qualifies as "establishment" in anything like the sense that Clinton, Kerry, Biden et al do. I certainly don't see how he's any more "establishment" than Warner or Richardson, for example. To say the very least. Part of the establishment flirted with him briefly in 03-04 as the only apparent alternative to Dean, but they dropped him like a cold fish as soon as their boy Kerry surprised everyone by actually winning Iowa. Gore has also moved quite a ways away from the establishment over the past couple of years. I know that Clark, Gore and Feingold all appeal in different ways to many people who are dissatisfied with or infuriated by the current establishment, and while I can't see the numbers I would suspect that there is probably a significant correlation between support for these three here as well. That's a hypothesis based on substantial anecdotal evidence, anyway.
