John Kerry has decided to endorse Barack Obama, the wine-track candidate running against the Democratic establishment, rather than his own running mate of four years ago, John Edwards. Is this eerily familiar to anyone else of Al Gore deciding to endorse Howard Dean, the wine-track candidate running against the Democratic establishment, rather than his own running mate of four years earlier, Joe Lieberman? The latter event, as I recall, preceded the complete collapse of Dean by a few weeks. Here's hoping that induction fails in this case.
