The Senate Finance Committee's passage on August 2 of legislation extending tax cuts known as "extenders" came as a welcome surprise to many. The package, cobbled together in the final week before the August recess by Committee Chairman Max Baucus (D-Mont.) and ranking member Orrin Hatch (R-Utah), would extend dozens of tax provisions set to expire at the end of the year. It cleared the committee by a bipartisan 19-5 vote.

Environmental groups and renewable-energy advocates were quick to praise the committee for passing the bill. But some observers say the legislation faces an uphill battle and may not see significant action until after the election.
