If one were to judge the fate of climate legislation based solely on public polling, it would appear that it is only a matter of time before the bill easily cruises through Congress and arrives on the president's desk. Hardly a week seems to go by without a new poll showing strong support for climate change legislation.

But if the adage that politicians follow public opinion is true, why are so many key lawmakers still on the fence over the legislation? Why are politically endangered Democrats hesitant to support a bill that the polls say that voters actually like? And why does the seemingly popular legislative item continue to slide further and further down the congressional agenda?
