I've seen references to "The Kool Kids" on this blog many times.
Based on the context, I think it might refer to the DLC, to Dean's Democratic presidential candidate opponents, to people who work on K Street, or other "establishment" types. On the other hand, "Kool" is spelled the same as it is in "Have you been drinking the Kool-Aid?" and Dean's supporters are mocked as being young only, which would suggest it refers to Dean supporters; but, it never seems to be used in that context.
So, please fill me in. What's the story behind "The Kool Kids"?
