This was a vote to move a large trade bill forward to passage. The bill had four main parts: the renewal of lower tariffs for imports from four South American countries; extension of the Generalized System of Preferences, a list of products from 140 countries that can enter the U.S. duty-free; "fast-track" trade negotiation status, which gave the president the power to submit trade agreements to the Senate for approval without the possibility of amendment; and an expansion of the Trade Adjustment Assistance program, which provided aid to American workers dislocated by trade agreements. The bill was a high priority for the Bush administration, primarily because of the fast track provision. Progressives disapproved of the bill because it made protecting American workers from overseas competition more difficult, especially given that many foreign competitors maintained weaker labor and environmental regulations. To bring the bill to a final vote, supporters had to invoke cloture, which limits the length and range of debate. Without cloture a bill often dies, so Progressives opposed cloture because they opposed the bill itself. The motion for cloture passed with eight votes to spare, 68-29, and the bill moved forward.
