Quick opinion: I think that the "ABB" (Anyone But Bush) path the Democratic candidates and their supporters seem to be taking is juvenile and a logical fallacy. Regardless of which side one is on, it makes very little sense to rely on such a playground-like slogan, especially as they are not just saying it jokingly. To me choosing the lesser of two evils is understandable and necessary in politics, but this tact approaches that idea from a different angle which to me seems half-blind at best, if not smugly self-superior.
