it's time we remind you who first declared Keith Olbermann overrated, because now, on the back of his latest series of popped capillaries, more people are calling him predictable and "edging ever-closer to self-parody." Could it be that the oh-sweet-baby-Jesus-make-it-stop, sans-anesthesia root-canal process that is the Democratic primary has driven him over the edge? Time's Swampland makes the point that "Every time he turns up the volume to 11 like this lately, he sounds like just another of the cable gasbags he used to be a corrective to." Yes, his position on Hillary Clinton's assassination invocation is well researched and thought out, but does it add anything other than volume to the discourse? Is Chris Matthews getting to Olbermann? Was last night's Special Commentary, above, the moment Keith jumped the shark?
