I've heard two superficially plausible and, I think, completely contradictory narratives of what the Rahm Emmanuel appointment means. One: that Barack Obama is taking his administration in a more pragmatic, less ideological direction. Two: that Barack Obama is looking for a hatchet man to beat the snot out of the Republicans. Which is true? I'm not enough of an insider to even hazard a guess. But it's interesting how the same piece of information can plausibly tell two utterly different stories.
