Supporters of legislation to curb global warming failed to overcome a procedural roadblock today in the Senate, falling 12 votes short of the 60 needed to limit debate on the bill.

The Senate voted overwhelmingly on Monday to begin debate on the bill, but the measure quickly became mired in partisan maneuvers on unrelated issues. Today the bill stalled on a 48-36 cloture vote. The measure was subsequently pulled from the floor.

By the time the Senate began voting this morning, supporters of the legislation offered by Sen. Barbara Boxer (D-Calif.), chairman of the Environment and Public Works Committee, were resigned to defeat. But many argued that the legislation was a first step in a debate that would continue with a more responsive president, as President Bush has threatened a veto if the bill reached his desk.

All week, GOP lawmakers pounded the proposal, arguing that it would further increase already soaring gasoline prices.

On Thursday afternoon, Minority Leader Mitch McConnell (R-Ky.) attempted to offer an amendment but Majority Leader Harry Reid (D-Nev.) objected, saying that the chamber would move to legislation on gas prices next week.
