How Ben Sasse Built a Structural Originalist Case for the Filibuster

Ben Sasse’s last and sharpest filibuster defense begins with a concession that many defenses of Senate practice try to avoid: the filibuster is not in the constitutional text. In his July 2026 Wall Street Journal op-ed, reprinted by the American Enterprise Institute, he wrote that the rule “isn’t in the text of the most glorious political document ever written,” then argued that America still needs it because the Constitution’s structure was designed to resist the consolidation of political power into one national majority, one party command, or one referendum-style mandate.[1]

That is the useful entry point into Sasse’s filibuster defense, because it prevents the easy version of the debate from taking over. Sasse was not claiming that Article I secretly contains a sixty-vote threshold for ordinary legislation. He was making a structural-originalist claim: the Constitution created a Senate meant to slow, separate, and complicate national power, and the modern filibuster, in his view, is the rule that makes that design operational.

The timing gave the piece a valedictory quality, but it should not be made to do legal work. The Hill reported that Sasse wrote after disclosing Stage 4 pancreatic cancer, following his resignation as University of Florida president.[2] That biographical fact explains why readers might hear the essay differently. It does not prove the constitutional claim. The claim has to stand, if it stands, on the theory Sasse had been building since his first year in the Senate.

The concession that makes the argument harder

The common pro-filibuster phrase “minority rights” is too thin for Sasse’s argument. It sounds like a free-floating fairness norm, and it invites an equally thin response: elections have consequences. Sasse’s 2026 version is more specific. He described the filibuster as serving an “anti-consolidation objective,” an unwritten constitutional principle he connected to Madisonian separation of powers and to the Framers’ distrust of concentrated authority.[1]

That move matters because it shifts the debate from text to structure. A textualist critic can say, accurately, that the Constitution specifies supermajority requirements in particular places and does not impose one for ordinary Senate legislation. Sasse’s answer is not to deny the omission. It is to say that constitutional meaning is not exhausted by enumerated voting thresholds. The separation of powers, bicameralism, staggered Senate terms, equal state representation, and the Senate’s internal rulemaking authority all express a design against sudden consolidation.

The vulnerable point is also the serious point. Once the argument depends on an unwritten objective, the burden increases. Sasse has to show not merely that the filibuster is old, useful, or politically convenient, but that it performs a function close enough to the constitutional design to justify preserving a rule that now operates as a routine supermajority requirement.

The Senate as an antidote, before the filibuster became the centerpiece

Sasse’s 2026 op-ed did not come from nowhere. In his maiden Senate speech on November 4, 2015, he described the Senate as an “antidote to sound-bites” and emphasized that the institution was designed to “insulate this body from the short-term passions of the moment.”[3] The filibuster was not yet the whole argument. The Senate itself was.

That first speech is important because it identifies the constitutional object Sasse later claims the filibuster protects. He saw the Senate not as a smaller House of Representatives, but as a deliberately awkward institution: slower, less majoritarian, less responsive to immediate national moods, and less compatible with a plebiscitary understanding of politics.

By January 2016, in a Wall Street Journal op-ed titled “Ending the Filibuster Would Hand Progressives a Huge Victory,” Sasse had attached that institutional theory to the filibuster itself. The rule, he argued, served a “distinctly conservative, and constitutional, purpose.”[4] “Conservative” in that formulation did not merely mean Republican advantage. It meant conserving a constitutional arrangement that frustrates the direct conversion of temporary electoral victory into comprehensive national law.

This is where Sasse’s defense becomes more interesting than ordinary Senate traditionalism. He was not simply praising delay. Delay can be empty. Nor was he treating every obstruction as deliberation. He was arguing that the Senate’s anti-majoritarian features need a procedural device strong enough to force cross-pressure, negotiation, and revision before national policy can move.

Four Senate features, one procedural keystone

The core of Sasse’s constitutional defense is a four-part account of Senate design. Six-year terms distance senators from every gust of electoral opinion. Equal state representation prevents national power from being reduced to population alone. Rules empowering individual senators keep members from becoming interchangeable party agents. The absence of formal party rules, in his account, leaves space for senators to deliberate as constitutional officers rather than as disciplined parliamentary votes.[1]

This is the most coherent version of his case. The four features do not independently prove the filibuster. Six-year terms still exist without it. Equal state representation still exists without it. Senators would retain some individual powers without it. The Senate would still not have formal party rules. Sasse’s claim is more functional: without a rule that lets a minority block or delay ordinary legislation, these features become atmospheric rather than operative.

On that view, the filibuster is not the constitutional design itself. It is the mechanism that activates the design when partisan pressure would otherwise flatten it. A senator serving a six-year term can resist a short-term wave, but resistance matters more if the chamber’s rules make immediate majority closure difficult. A small-state senator can represent a state on equal terms, but equal representation has sharper consequences when a coalition cannot simply pass legislation by bare national party majority. An individual senator can speak, object, and bargain, but the filibuster converts those acts from ceremony into power.

That is why Sasse’s argument is better described as structural originalism than as Senate nostalgia. He is asking readers to infer a constitutional purpose from institutional architecture, then to defend a later procedural rule because it performs that purpose under modern party conditions.

The 2021 Biden maneuver showed the argument’s political ambition

In March 2021, Sasse defended the filibuster by reading Joe Biden’s 2005 defense of it back into the record. Biden had warned that abolishing the rule would “eviscerate the Senate” and “upset the constitutional design,” and Sasse used those words to argue that the institutional concern had once crossed partisan lines.[5]

The move was theatrical, but not merely theatrical. It tried to separate the constitutional argument from immediate partisan ownership. If Biden could defend the filibuster when Republicans held power, Sasse could claim that the relevant principle was not Republican obstruction, but a recurring institutional fear: each majority is tempted to destroy restraints when it finally controls the agenda.

Still, the argument from past bipartisan rhetoric has limits. Politicians often defend restraints they need and denounce restraints they resent. Biden’s 2005 words supplied evidence that the constitutional vocabulary of Senate preservation was once politically portable. They did not settle whether the modern rule is constitutionally justified.

A defender of an institution he thought was failing

Sasse’s January 3, 2023 farewell address adds a complication that should not be tidied away. He called the Senate “increasingly irrelevant,” even as he continued to defend its deliberative purpose.[6] That tension is part of the record. He was not describing a healthy chamber in need of minor appreciation. He was defending an institutional ideal against the institution’s own decay.

The point matters for the filibuster because a rule can be justified at one level of theory and corrosive in a changed operating environment. Sasse’s account depends on the filibuster inducing deliberation. The modern Senate often uses it without sustained floor debate. The silent filibuster, where obstruction can occur through notice and expectation rather than a senator physically holding the floor, is a poor fit for the civic drama that filibuster defenders sometimes invoke.

Sasse’s strongest version avoids the theatrical defense and instead says that even a less romantic filibuster forces broader agreement before lawmaking. But that is a different claim from saying the rule produces deliberation. It may produce bargaining, narrowing, delay, or abandonment. Whether those effects count as constitutional goods depends on the baseline one accepts.

The SAVE America Act fight is context, not the center

As of July 23, 2026, the current fight over the SAVE America Act has made the filibuster newly concrete. Roll Call reported on June 25, 2026, that President Trump demanded filibuster abolition, Senate Majority Leader John Thune said the votes did not exist, and House Freedom Caucus members attacked the Senate as “lazy” amid the voter-ID clash.[7] The Legislative Procedure Blog argued on July 14, 2026, that the impasse reflected bipartisan inaction more than the filibuster alone.[8]

That episode is useful mainly because it shows the pressure Sasse’s theory is meant to resist. A national party wants a bill. The House wants the Senate to move. The president wants the procedural barrier removed. The Senate majority leader says the votes are not there. In ordinary political language, that is dysfunction. In Sasse’s constitutional language, the same friction may be the system refusing consolidation.

But the current fight should not be allowed to swallow the analysis. If the filibuster is defended only because one likes the bill being blocked, the constitutional argument has already been lost. Sasse’s claim requires the rule to be defensible when it frustrates one’s preferred coalition.

The modern filibuster is not the exceptional device Sasse’s theory wants

The hardest empirical problem for Sasse is not that the filibuster is absent from the constitutional text. He admits that. The harder problem is that the rule he defends as an instrument of deliberative constitutional structure has become a standing supermajority requirement for much of Senate business. The Brennan Center reports that from 1917 through 2006 there were 960 cloture motions, an average of 11 per year; in the 14 years after 2006, there were 1,037, an average of 88 per year.[9]

Those numbers do not prove the filibuster unconstitutional. They do show that the operating reality has changed. A device used episodically to force extended debate is one thing. A default condition under which ordinary legislation is presumed to need sixty votes is another. Structural arguments must account for structure as it functions, not only as it appears in institutional theory.

This is where a careful defense of Sasse must distinguish deliberation from obstruction. The Constitution plainly tolerates delay. Bicameralism itself is delay. Presentment is delay. Staggered Senate terms are delay. The question is whether today’s filibuster produces the kind of deliberative friction Sasse describes, or whether it converts the Senate into a body where a minority veto is expected before debate has meaningfully begun.

Three objections Sasse’s theory has to answer

The Hamiltonian and textualist objection

The first objection is majoritarian. Critics invoke Alexander Hamilton’s warning in Federalist No. 22 that giving a minority a negative over the majority tends “to subject the sense of the greater number to that of the lesser.” The Princeton Legal Journal’s anti-filibuster argument uses that premise to contend that the modern sixty-vote rule conflicts with the Constitution’s implicit majoritarian structure.[10]

Josh Chafetz similarly argues that the Constitution’s design and historical practice do not support an entrenched minority veto over ordinary legislation.[11] This line of critique is not simplistic textualism. It reads the Constitution’s specified supermajority requirements as evidence that ordinary lawmaking was meant to proceed by majority vote unless the document says otherwise.

Sasse’s answer would be that the Senate is not a simple majoritarian institution and was never meant to be. The Constitution gives Wyoming and California equal Senate votes, staggers elections, and divides lawmaking among institutions. The textualist counter-answer is that those anti-majoritarian choices are the ones the Constitution actually made; adding a routine sixty-vote threshold is not interpretation but supplementation.

The historical-accident objection

The second objection is historical. Sarah Binder’s account for Brookings undercuts any simple claim that the Framers designed the filibuster as such. The Senate dropped the “previous question” motion in 1806 on Aaron Burr’s recommendation, the first filibuster did not occur until 1837, and the Senate did not adopt cloture under Rule XXII until 1917.[12]

That chronology is not fatal to every structural defense. Many constitutionally significant practices develop after ratification. But it is fatal to the lazy version that treats the filibuster as if it were a consciously designed Founding-era instrument. Sasse’s more careful argument has to be that the rule later came to serve a constitutional function latent in the Senate’s design, not that the Framers specifically created the filibuster.

The Article I rulemaking defense, and its limit

The third position is more favorable to the filibuster but still distinct from Sasse’s. Michael Gerhardt defends the filibuster under Article I, Section 5, which gives each chamber authority to “determine the Rules of its Proceedings.”[13] That is a rulemaking-power argument. It says the Senate has constitutional authority to choose rules like the filibuster.

Sasse’s argument goes further. He does not merely say the Senate may adopt the filibuster. He says the filibuster protects a constitutional objective central to the Senate’s design. Article I, Section 5 can explain why the rule is permissible. It does not, by itself, explain why eliminating the rule would betray the Constitution’s structure.

What the anti-consolidation objective adds

The “anti-consolidation objective” is Sasse’s final refinement because it names the constitutional harm he thinks filibuster abolition would cause. The harm is not simply faster lawmaking. It is the conversion of congressional politics into national plebiscite: one election, one asserted mandate, one party program, one demand that the Senate yield. In the 2026 op-ed, he warned against “European-style referenda” and “Flight 93 elections,” phrases aimed at politics that treat each national contest as existential and winner-take-all.[1]

This is more ambitious than a prudential defense of Senate delay. Sasse is saying the filibuster helps prevent Congress from becoming another instrument of the same nationalized partisan combat that already dominates presidential elections and House races. The Senate’s distinctive features matter only if they can resist that gravitational pull. Without the filibuster, he fears, six-year terms and equal state representation remain formally intact while party majorities functionally consolidate power.

The strongest form of the claim is not that every filibuster is noble. It is that a constitutional system designed to fragment power needs some procedural devices that make fragmentation costly to overcome. The filibuster supplies one such device inside the Senate itself, where party leaders otherwise have strong incentives to make the chamber resemble the House.

The weakest point is the size of the inference. Madisonian structure clearly resists consolidated power. It does not clearly prescribe the modern filibuster. To accept Sasse’s conclusion, one must accept that an unwritten anti-consolidation principle can justify preserving a later-developed Senate rule even after that rule has become routine, silent, and often detached from extended public deliberation.

A coherent defense, if one accepts the unwritten premise

Sasse built one of the more coherent constitutional defenses of the filibuster precisely because he did not pretend the text settles the issue. His case is not that the Constitution says “filibuster.” It is that the Constitution created a Senate meant to frustrate consolidation, and that the filibuster has become the procedural keystone that lets the Senate’s anti-majoritarian features do real work.

That defense deserves more careful treatment than partisan scorekeeping gives it. It also deserves more skepticism than institutional sentimentality gives it. The modern Senate is not simply the deliberative chamber of Sasse’s theory, and the modern filibuster is not simply extended debate. The constitutional question is whether the anti-consolidation principle he identifies is strong enough to justify today’s routinized supermajority Senate. Sasse’s answer was yes. The Constitution’s text leaves enough silence for the argument to be made, but not enough to make it unavoidable.
