Not exactly. There have been no marathon debates in the Senate about health care or the stimulus bill. Senators aren't sleeping on cots in the chamber as aides ferry coffee to some lone Republican passionately making his case that the president wants to socialize medicine. The way Senate rules currently work, the minority party merely has to announce its intent to filibuster if it wants to stop a piece of legislation. Senate Majority Leader Harry Reid could force the Republicans to actually go through with it, but the way the rules work, the filibuster actually puts the onus on the majority, not the minority, to keep the debate going. A lone dissenter can object to a motion to end debate by universal consent, but if the majority fails to keep a quorum in the chamber at any given time, the Senate can be forced to adjourn.
