Washington ? The Senate expressed strong, bipartisan disapproval of President Bush’s policy on Iraq in a rare Saturday session, but lawmakers nevertheless failed to end their debate and pass a nonbinding resolution.

One day after the House issued its stinging rebuke to Bush’s plan to boost the number of troops in Iraq, the Senate was unable to muster the 60 votes necessary to end a Republican filibuster and pass what has become an important symbol of resistance to the war.

It was the second time in recent days that the Senate was stymied by parliamentary rules requiring the consent of a supermajority before any action could be taken on the anti-war resolution.

The vote was 56-34, with 7 Republicans joining 49 Democrats.

Frustrated Democrats vowed to continue to press the Iraq issue in the coming weeks on a bill to implement the recommendations of the Sept. 11 Commission. But they conceded that the resolution itself is dead. Meanwhile, the administration has already begun shoring up combat troops in Baghdad by 21,500 regardless of congressional action.

“The Senate is not done with this issue,” Senate Majority Leader Harry Reid, D-Nev., declared after the vote. “It’s too important to be brushed aside.”

Angry Republicans insisted that the language in question would demoralize American soldiers fighting in Iraq. And they rejected assertions that their filibuster was preventing the Senate from debating the merits of the war strategy.

“Here is the truth that the American people need to know: Republicans in the Senate have not prevented any debate over the war in Iraq,” said Sen. Jim Bunning, R-Ky. “We are debating the war again today. We have debated the war in the past and we will continue to debate the war in the future.”

Many senators expressed disgust that they had been dragged into work on the weekend, accusing Democrats of gamesmanship.

Sam Brownback, R-Kan., made a show of breezing through – he put on his overcoat immediately after voting and left with his briefcase, rushing to catch a plane to Orlando, Fla., where he was to address religious broadcasters – while fellow Kansas Republican Pat Roberts wore a blue scarf around his neck and playfully swatted colleagues with his driving cap.

Sen. Lindsey Graham, R-S.C., complained that the Senate was “playing stupid political games” as Reid refused to allow debate on multiple resolutions. And he challenged those that oppose the war to vote to cut off funding, rather than supporting a message of disapproval.

“This is a very, very sad Saturday for the U.S. Senate on the heels of a disaster in the U.S. House, where a majority, a bare majority, of the House wants to send a political message at a time of war that doesn’t keep one person from being shot at,” Graham said.

The House vote rebuking Bush’s war plan was 246-182, with 17 Republicans voting in the majority.
