I don't know enough about the economics of climate change to weigh in -- Conor Clarke and Jim Manzi should give you a good representation of the arguments -- but from the perspective of institutional politics, I'd say that the winners tonight are Speaker Nancy Pelosi's ability to corral her caucus behind legislation that would disproportionately hurt some of their districts is perhaps the greatest accomplishment of her tenure; the persistence of Henry Waxman and Ed Markey, who insisted on moving this bill forward even though the White House was skeptical, and the nimble rulemaking of Louise Slaughter, who managed the amendments process in a way that gave just enough Republicans and Democrats just enough of a reason to support it. It's on to the Senate, where longtime climate skeptic James Inhofe says it's DOA. We will see.
