It's difficult to picture this being a good move for Howard Dean. Joe Trippi, by most accounts, deserves a great deal of the credit for infusing the Dean campaign with an organizing approach that the Democrats have largely forgotten over the past couple decades, and by all accounts was central to Dean's tremendous rise over the past year. Replacing him with a Gore operative, further, risks the appearance or worse the reality of trying to reassure voters by embracing the establishment that's disenfranchised so many of them from the process. When Gore endorsed Dean I argued that it demonstrated more about Gore and his recognition of the failures of his "lockbox" campaign than about Dean; it would be a shame if Dean plans to regain his lead by becoming Al Gore circa 2000. Or, for that matter, John Kerry circa 2003.
