WASHINGTON (CNN) - An effort to require better mileage from U.S. cars and trucks failed in its bid for a full Senate vote Friday morning, 53 to 42.
Opponents of the measure, which passed the House Thursday, had threatened to filibuster the bill, and its supporters could not muster the 60 votes required to bring it to a full vote.
The bill, which was opposed by President Bush, would have ended some tax loopholes for the oil industry and used those funds to extend tax credits for renewable energy sources.
Senate Majority Leader Harry Reid, D-Nevada, had said earlier that he would require the four Senate Democrats currently on the presidential campaign trail to return to Washington if the bill came up for a full vote this weekend.
