Senate Democrats refused to flinch Tuesday as the chamber moved toward a rare, all-night session of debate on legislation to bring troops home this fall.
They called for sleeping cots to be rolled into a room off the Senate floor and told members to prepare for repeated votes throughout the evening.
The legislation, proposed by Senators Carl Levin, D-Mich., and Jack Reed, D-R.I., would order troops to start leaving in 120 days and complete the pullout by April 30, 2008.
The goal of the planned marathon debate was to test the patience of Republicans, who have threatened to filibuster the bill.
So far, the GOP leadership has been successful at blocking anti-war legislation because Democrats don't have the 60 votes to cut off what would become an endless debate on the war.
Republicans dismissed the maneuver as political theater and said the Senate should vote forgo the debate and vote immediately on whether to advance the measure.
Whether the vote comes Tuesday or Wednesday, the proposal is expected to gain a majority of senators, but not reach the 60-vote threshold.
"If we leave Iraq prematurely, jihadists around the world will interpret the withdrawal as their great victory against our great power," said Sen. John McCain of Arizona, the top Republican on the Armed Services Committee.
Under the bill, an unspecified number of troops could remain behind to fight terrorists, protect U.S. assets and train Iraqi security forces.
Republicans mostly have been united against setting a timetable for troop withdrawals, but GOP leaders have told the White House their job of retaining support for the war will become exponentially harder after September. Many Republicans say they want to see substantial progress by then.
That message was relayed in a private gathering Monday at the White House of GOP congressional staffers and Bush aides trying to determine an effective strategy for communications about war policies. Bush made a surprise visit to the meeting, telling the staffers he would not rethink his Iraq policies until after a critical military assessment in September, one participant said.
Bush also said he had no confidence in the ability of international institutions — a reference to the United Nations — to salvage Iraq if the U.S. were to withdraw, according to the participant, who spoke anonymously because the meeting was intended to be private.
