But even if a compromise can be reached on that portion of the bill, that's no guarantee that it can pass the Senate by Friday. Reid also plans to bring a new jobs package to the floor this evening, and the Senate has yet to vote on the confirmation of Supreme Court nominee Elena Kagan -- both of which will eat up significant floor time.
Even if it can all be cleared in theory, other policy differences may stymie the energy package anyhow. Democrats have been extremely cautious with their language, noting that each of the bill's four provisions has, on its own, bipartisan support. But that's a far cry from saying the whole package has bipartisan support, and can overcome a filibuster with 60 votes.
