I find it really annoying when liberals, Atrios for example, get annoyed at pundits who focus on style. Does anyone think Clinton ran on substance? Clinton, Carville et al. understood that politics is theater. It's packaging. Dean understands this more than most, Clark less so (Mark Kleiman's fandom, in this context, is amusing) and Lieberman is the definition of an incompetent: one who does not realize his own incompetence.
