In case you didn't notice, over the last few days we entered a new phase in the Obama presidency: the scandal phase. What happened? It wasn't evidence of a crime being unearthed, or a confession from a conspirator. There was no sudden revelation, no arrests, no cancer on the presidency. Indeed, just a few days ago it looked for all the world like Benghazi would take its place with Solyndra and "Fast and Furious" as one more wished-for scandal that, despite the best efforts of Republicans, failed to take flight. Yet all it took was ABC News getting passed some emails between the CIA, the State Department, and the White House detailing how the administration argued over how exactly to talk about the attack in Benghazi to get things underway, and now we have calls for special committees and ramped-up coverage. There may not be anything particularly shocking in those emails—just the time-honored tradition of people trying to cover their asses—but some internal deliberations being revealed, no matter what they contain, has given the media enough of a prod to start that scandal train moving, and before you know it everyone's going to jump onboard.
So suddenly it looks like this isn't going away, not because there was appalling malfeasance (or any malfeasance at all), but because once the train is moving, it's almost impossible to stop. Put together the right's desperate longing for an Obama scandal—turn on Fox News or listen to conservative radio, and you'll see eyelids fluttering in ecstasy as this story gains momentum—with congressional Republicans' helplessness in the face of pressure from their base, and the media's inability to resist a presidential scandal story, and this whole thing might not end unless and until Barack Obama is impeached.
