"Of course he had to go." ?
He had to go because the voters rejected him. Someone should remind Rall this is a bit different than, say, being martyred. Rall seems to see "Howard's End" as only a slight variation on being murdered. Look at the category he puts Dr. Dean in:
"Usually, when an American political figure speaks truth to power, he ends up conveniently dead. RFK, Malcolm X, some say Minnesota Senator Paul Wellstone."
Too much of a stretch, Ted. Bobby Kennedy and Malcom (X) Shabaz were murdered 36 and 40 years ago respectively and only RFK was (probably) killed by the powers that be. Shabaz was murdered by Islamic extremists, not exactly zealots of the American establishment. Wellstone, of course, died in a plane crash.
In the generation since those tragedies hundreds of activists have come along and taken up the noble struggles of these great men without getting shot. I guess you could argue that Dean was in their mold, if not exactly their footsteps. But his "wounds" were entirely self-inflicted. He didn't fail to take off because the networks made too big a deal out of his "rambunctuous" "concession" speech in Iowa. Sure, they did make too big a deal out of it, but that night on DU, right as he made the speech the reactions of DUers, including his supporters, ranged from mild WTFs to suggestions that he had "lost it" or was "freaking out".
But the real reason he lost the votes was that his message didn't gel and his personality thru all his campaign appearances just didn't add up to Oval Office material. From his mixed political record (tiny state, big prison builder, ineffectual Dixicrat pandering, NRA rating) to his McCarthyistic tendency to call everyone a Republican whenever he disagreed with them, he did not present himself as a guy who would be everybody's president.
Howard Dean won't be president, at least not this year. He won't get there because he shot himself in the foot. That's what you get when you stick you foot in your mouth while you're shooting your mouth off. It's not the same as being murdered. It doesn't take a conspiracy. It just takes being a second rate politician.
