Filibuster: The Senate’s Controversial Blocking Tactic

What’s a filibuster?

A filibuster is a parliamentary procedure use in the U.S. senate that allow senators to block or delay legislation by extend debate indefinitely. The term come from the Dutch word” vrijbuiter,” mean” freebooter” or” pirate,” which evolve into the Spanish” filibuster” reflect its middling disruptive nature in the legislative process.

Unlike the House of Representatives, which limit debate time, the senate traditionally permits unlimited discussion onpencee legislation. This rule create the opportunity for the filibuster, where senators can efficaciously prevent a vote on a bill by continue to speak on the senate floor.

How a filibuster works

In its traditional form, a filibuster requires senators to physically stand and speak on the senate floor incessantly. Thes” talk filibusters” create dramatic scenes in aAmericanpolitical history, with senators read phone books, recipes, or the constitution to maintain control of the floor.

The modern filibuster seldom requires such physical endurance. Today, a senator simply will need to will indicate an intention to filibuster, which will signal that the measure will require a 60 vote supermajority( out of 100 senators) to will proceed quite than a simple majority. This procedural evolution has make filibusters often more common in recent decades.

Closure: the filibuster’s counterweight

To overcome a filibuster, the senate can invoke” cclosure ” procedure establish in 1917 that limit further debate. Initially require a twtwo-thirdsajority, the threshold was rereducedo three fifths ((0 votes ))n 1975. The cloclosureocess include:

File a closure petition sign by astatine least 16 senators
Wait one full legislative day
Hold a vote require 60 senators to support end debate
If successful, allow a maximum of 30 additional hours of debate before a final vote

Historical evolution of the filibuster

The filibuster wasn’t created deliberately but emerge as an unintended consequence of senate rules. The senate’s original rules include a provision know as th” previous question” motion that allow a simple majority to end debate. In 1806, at the suggestion of vice president aAaronburr, this rule was eeliminated unknowingly create the possibility for unlimited debate.

For much of the 19th century, the filibuster remains a seldom use tactic. Its prominence grow importantly during the 20th century, especially around civil rights legislation.

Key milestones in filibuster history

1917:

The senate adopt rule 22, establish the closure procedure to limit debate
1949:

Rule 22 was modified to require two-thirdsds vote of senators present and vote
1975:

The threshold was lower to three fifths of all senators (60 votes )
2013:

The” nuclear option ” as usused toliminate filibusters for executive branch nominations and federal judicial appointments ((xcept the supreme court ))
2017:

The filibuster exception was extended to supreme court nominations

Famous filibusters in American history

The filibuster has produced some remarkable moments in senate history, withseveral standsd out for their duration or historical significance:

Storm Thurmond’s record break stand

The longest individual filibuster in senate history was conduct by senator storm Thurmond of South Carolina, who speak for 24 hours and 18 minutes in opposition to the civil rights act of 1957. Thurmond prepares for his marathon speech by take steam baths to dehydrate himself( thusly he wouldn’t need bathroom breaks) and bring throat lozenges and malt milk tablets to sustain himself.

The southern bloc and civil rights

Perchance the virtually consequential use of the filibuster come from southern senators oppose civil rights legislation in the mid 20th century. In 1964, opponents of the civil rights act stage a 60-day filibuster â€” the longest in senate history â€” before supporters eventually achieve closure.

Bernie Sanders’ budget protest

In 2010, senator Bernie Sanders hold the floor for over eight hours to protest a tax deal, deliver what became known as th” Filiberto. ” wWhilenot technically a filibuster ((s it didn’t block a vote ))it demdemonstratesw a senator could use extended speaking time to draw attention to an issue.

Rand Paul’s drone strike filibuster

In 2013, senator Rand Paul conduct a virtually 13 hour filibuster to delay the nomination of john Brennan as CIA director, demand clarification on the Obama administration’s drone policy. This represents a more traditional use of the filibuster to extract information or concessions.

The modern filibuster: silent but powerful

The contemporary filibuster bears little resemblance to its theatrical predecessor. Today’s version is oftentimescalled” ” sile” ” o” virtual” filibuster because it rrequiresno speak marathon. Rather, the mere threat of a filibuster is ordinarily sufficient to halt legislation that lack 60 supporters.

This evolution has dramatically increased the use of the procedure. While filibusters were rare occurrences for most ofAmericann history, they’ve become routine in recent decades. During the 1950s, there be fewer than oneclosuree motion file per year on average. In recent sessions of congress, that number has regularlyexceededd 100.

The two track system

A significant change come in the 1970s when senate majority leader mike Mansfield implement a” two track ” ystem allow the senate to set divagation filibuster bills and continue with other business. While this keep the senate functioning, it toto makeilibusters less costly for the obstruct party, as they nobelium hanker have to hold the floor incessantly.

Arguments for and against the filibuster

Few senate procedures generate equally often passionate debate as the filibuster. Supporters and critics both make compelling arguments about its role in American democracy.

Defend the filibuster

Proponents argue that the filibuster:

Protect minority rights:

It prevents a slim majority fromsteam rolll the minority party’s concerns
Encourages compromise:

The 60 vote threshold forces bipartisan cooperation on major legislation
Provide stability:

It prevents dramatic policy swings when control of government changes hands
Maintain the senate’s distinctive role:

It preserves the senate’s tradition as the more deliberative body compare to the house

Criticize the filibuster

Critics contend that the filibuster:

Undermines majority rule:

It allows a minority of senators to block the will of the majority
Create dysfunction:

It contributes to legislative gridlock and government inefficiency
Lack constitutional basis:

The founders ne’er intend supermajority requirements for ordinary legislation
Have a troubling history:

It was conspicuously used to block civil rights legislation

Reform proposals

As frustration with senate gridlock has grown, various reforms have beenproposede to modify the filibuster without eliminate it totally:

Talk filibuster restoration

Some reformers advocate return to the” talk filibuster, ” equire senators to really hold the floor and speak incessantly to maintain their objection. This would make filibuster more physically demanding and publically visible.

Reduce the threshold

Others suggest gradually reduce the 60 vote threshold to end debate, perchance start at 57 and finally move to 55 or 51 votes.

Issue specific exemptions

Another approach would create exemptions for specific types of legislation, similar to the budget reconciliation process that already allow certain fiscal measures to pass with a simple majority.

Shift the burden

Some propose invert the burden, require 41 senators to actively maintain a filibuster instead than require 60 to break it. This would force the object minority to maintain a constant presence on the senate floor.

The filibuster in contemporary politics

The debate over the filibuster intensifies whenever control of the senate change hands. Typically, the majority party criticize the procedure while the minority defend it, with many senators reverse their positions when their party status changes.

This pattern reveal an important truth: the filibuster debate isn’t strictly about principle but besides about power. The procedure’s value to individual senators depend mostly on whether they’re tried to pass legislation or block it.

The nuclear option

The virtually dramatic change to the filibuster come through the indeed call” nuclear option”â€”change senate rules with a simple majority vote instead than the ttwo-thirdsmajority traditionally require for rules changes.

In 2013, democratic majority leader Harry Reid use this approach to eliminate the filibuster for executive branch nominations and federal judicial appointments (except for the supreme court ) In 2017, republican majority leader miMitch McConnellxtend this exception to supreme court nominations.

These precedents raise the possibility that a future senate majority could eliminate the legislative filibuster exclusively through the same mechanism.

The filibuster’s future

The filibuster stand at a crossroads in American politics. As polarization increases and the pressure to deliver legislative victories intensifies, the 60 vote threshold face unprecedented scrutiny.

Several factors will probable will influence the filibuster’s future:

Electoral outcomes:

Which party control the senate and by what margin
Public opinion:

Whether voters prioritize bipartisanship or legislative accomplishment
Institutional norms:

How senators value senate traditions versus policy goals
Specific issues:

Whether certain priorities generate enough pressure to trigger rules changes

Whatever its fate, the filibuster remainsana unambiguouslAmericanan institution that reflect the senate’s dual identity as both a democratic body and a deliberative one design to cool the passions of majority rule.

Conclusion

The filibuster embody the tension at the heart of American democracy â€” between majority rule and minority rights, between action and deliberation, between change and stability. Its controversial nature will ensure it’ll remain a focal point in debates about how our government should, will function.

Understand this procedural tool provide insight not simply into how legislation pass or fail, but into the fundamental character of American governance. The filibuster’s story is, in many ways, America’s story â€” complex, contradictory, and endlessly evolve.
