Via Brian Beutler, looks like Henry Waxman won an important vote today, netting the Steering and Policy Committee's endorsement to supplant John Dingell as chair of Energy and Commerce on a 25-22 vote. The full Democratic Caucus will vote tomorrow, and it's still unclear how that will fall, but this is a good sign for Waxman, and evidence that even if Dingell survives, he'll be well aware of the fragility of his position.
