1 Boring Old Man

cloture – The only procedure by which the Senate can vote to place a time limit on consideration of a bill or other matter, and thereby overcome a filibuster. Under the cloture rule (Rule XXII), the Senate may limit consideration of a pending matter to 30 additional hours, but only by vote of three-fifths of the full Senate, normally 60 votes.

filibuster – Informal term for any attempt to block or delay Senate action on a bill or other matter by debating it at length, by offering numerous procedural motions, or by any other delaying or obstructive actions.

History

Early use

In 1789, the first U.S. Senate adopted rules allowing the Senate "to move the previous question," ending debate and proceeding to a vote. In 1806, Aaron Burr argued that the motion regarding the previous question was redundant, had only been exercised once in the preceding four years, and should be eliminated. The Senate agreed, and thus the potentiality for a filibuster sprang into being. Because the Senate created no alternative mechanism for terminating debate, the filibuster became an option for delay and blocking of floor votes.

The filibuster remained a solely theoretical option until 1841, when the Democratic minority tried to block a bank bill favored by the Whig majority by using this political tactic. Senator Henry Clay, a promoter of the bill, threatened to change Senate rules to allow the majority to close debate. Missouri Senator Thomas Hart Benton rebuked Clay for trying to stifle the Senate’s right to unlimited debate and he was unsuccessful in eliminating the filibuster with a simple majority vote.

The 20th century and the emergence of cloture

In 1917 a rule allowing for the cloture of debate (ending a filibuster) was adopted by the Democratic Senate at the urging of President Woodrow Wilson. From 1917 to 1949, the requirement for cloture was two-thirds of those voting.

In 1946 Southern Democrats blocked a vote on a bill proposed by Democrat Dennis Chavez of New Mexico (S. 101) that would have created a permanent Fair Employment Practices Committee (FEPC) to prevent discrimination in the work place. The filibuster lasted weeks, and Senator Chavez was forced to remove the bill from consideration after a failed cloture vote even though he had enough votes to pass the bill. As civil rights loomed on the Senate agenda, this rule was revised in 1949 to allow cloture on any measure or motion by two-thirds of the entire Senate membership; in 1959 the threshold was restored to two-thirds of those voting. After a series of filibusters led by Southern Democrats in the 1960s over civil rights legislation, the Democrat-controlled Senate in 1975 revised its cloture rule so that three-fifths of the Senators sworn (usually 60 senators) could limit debate. Changes to Senate rules still require two-thirds of Senators voting. Despite this rule, the filibuster or the threat of a filibuster remains an important tactic that allows a minority to affect legislation. Strom Thurmond (D/R-SC) set a record in 1957 by filibustering the Civil Rights Act of 1957 for 24 hours and 18 minutes, although the bill ultimately passed. Thurmond broke the previous record of 22 hours and 26 minutes set by Wayne Morse (I-OR) in 1953 protesting the Tidelands Oil legislation.

The filibuster has tremendously increased in frequency of use since the 1960s. In the 1960s, no Senate term had more than seven filibusters. In the first decade of the 21st century, no Senate term had fewer than 49 filibusters. The 1999-2002 Senate terms both had 58 filibusters.
