 You've probably been hearing a lot about the filibuster these days, but here's one thing about this old Senate rule you might not know. The filibuster actually violates the Constitution. 41 Senate Republicans, who represent only 21% of the American population, are blocking the For the People Act, which is supported by 67% of Americans. They're also blocking an increase in the minimum wage to $15 an hour, supported by 62% of Americans. And so much else. Even some so-called moderate Democrats like Joe Manchin and Kristen Sinema have outsized power to block crucial legislation thanks to the filibuster. Many of those who defend the filibuster consider themselves originalists who claim to be following the Constitution as the framers intended. But the filibuster is not in the Constitution. In fact, the framers of the Constitution went to great lengths to ensure that a minority of senators could not thwart the wishes of the majority. After all, a major reason they called the Constitutional Convention was that the Articles of Confederation, the precursor to the Constitution, required a super-majority vote of nine of the thirteen states, making the government weak and ineffective. James Madison argued against any super-majority requirement, writing that the fundamental principle of free government would be reversed, and it would be no longer the majority that would rule, the power would be transferred to the minority. Alexander Hamilton, meanwhile, warned about how much good may be prevented and how much ill may be produced if a minority in either House of Congress had the power of hindering the doing what may be necessary. Hence the framers required no more than a simple majority vote in both Houses of Congress to pass legislation. They carved out specific exceptions requiring a super-majority vote only for rare high-stakes decisions, impeachments, expulsion of members, overriding a presidential veto, ratification of treaties, and constitutional amendments. By being explicit about these exceptions where a super-majority is necessary, the framers underscored their commitment to majority rule for the normal business of the nation. They would have balked at the notion of a minority of senators continually obstructing the majority, which is now the case with the filibuster. So where did the filibuster come from? Well, the Senate needed a mechanism to end debate on proposed laws, and move laws to a vote. A problem the framers did not anticipate. But in 1841, a small group of senators took full advantage of this oversight to stage the first filibuster. They hoped to hamstring the Senate and force their opponents to give in by prolonging debate and delaying a vote. This was what became known as the Talking Filibuster, as popularized in the film Mr. Smith Goes to Washington. But the results were hardly admirable. After the Civil War, the filibuster was used by Southern politicians to defeat legislation to protect the voting rights of black Americans. In 1917, as a result of pressure from President Woodrow Wilson and the public, the Senate finally adopted a procedure for limiting debate and ending filibusters with a two-thirds vote, sixty-seven votes. In the 1970s, the Senate reduced the number of votes required to end debate down to sixty, and no longer required constant talking to delay a vote. Forty-one votes would do it. Throughout much of the 20th century, despite all the rule changes, filibusters remained rare. Southern senators mainly used them to block anti-lynching, fair employment, voting rights, and other critical civil rights bills. That all changed in 2006, after Democrats won a majority of Senate seats. Senate Republicans, now in the minority, used the sixty-vote requirement with unprecedented frequency. After Barack Obama became president in 2008, the Republican minority blocked virtually every significant piece of legislation. Nothing could move without sixty votes. In 2009, a record sixty-seven filibusters occurred during the first half of the 111th Congress, double the entire twenty-year period between 1950 and 1969. By the time the 111th Congress adjourned in December 2010, the filibuster count had ballooned to 137. Now we have a total mockery of majority rule, and it bears repeating that just forty-one Senate Republicans, representing only twenty-one percent of the country, are blocking critical laws supported by the vast majority of Americans. This is exactly the opposite of what the framers of the Constitution intended. They unequivocally rejected the notion that a minority of senators could obstruct the majority. Every time Republicans use or defend the filibuster, they're directly violating the Constitution, the document they claim to be dedicated to. How can someone profess to be an originalist and defend the Constitution while repeatedly violating it? Senators whose votes have been blocked by a minority should have standing to take this issue to the Supreme Court. And the court should abolish the filibuster as violating the U.S. Constitution.
