When the Senate debated climate change legislation earlier this decade, it generally was understood the bill had no chance of becoming law. Floor debates in 2003 and 2005 came about after high-profile senators forced votes to score political points and embarrass the George W. Bush administration. Just one committee wrote last year's cap-and-trade bill, which crashed on the floor and became a political liability for Senate Democrats. This time around, Senate Democrats are trying another approach. They have set out to work as a team, with six separate committees trying to write language that can build ownership among influential swing votes well before the floor debate begins.
