A filibuster is a term for any tactic used to delay a vote in the U.S. Senate. The best-known filibustering method involves a senator (or group of senators) holding the floor for an indefinite period of time. This extends the debate on a bill (or the motion to consider the bill) indefinitely, potentially obstructing Senate business and distrupting the personal lives of the senators themselves. In order to bring a debate to a close, a process called cloture is used. Cloture limits further consideration of a measure to 30 hours and prevents the introduction of new amendments to that measure (in other words, only amendments that were introduced prior to cloture may be put to a vote). However, cloture requires a 3/5 majority (currently, 60 votes) to pass.
Recently, it has become a common practice in the senate to vote for cloture on many bills prior to the start of formal debate to head off the threat of a filibuster. While the Senate's rules of procedure do not explicitly require that a bill under cloture rules have a supermajority to pass, an agreement at the close of debate to require a 3/5 majority for passage of a measure is customary. This custom allows for the possibility of senators who oppose a bill to vote for cloture so that public debate can be held, but also means that supermajorities are often neccesary for the passage of bills through the U.S. Senate.
