Glossary on the Republic
Filibuster
UnionThe word for talking a bill to death comes from a word for pirate, and the longest one ever ran past twenty-four hours straight.
Filibuster comes from the Dutch vrijbuiter, a freebooter or pirate. It crossed into English through the Spanish filibustero and was pinned on the Senate tactic in the 1850s, because holding the floor to block a vote is, in effect, hijacking the ship of debate.
The mechanics are simple. In the Senate most bills need just a simple majority to pass, but ending debate takes a supermajority. So a senator who will not stop talking, and who has the votes to prevent debate from being closed, can keep a bill from ever reaching the vote it would win.
The record is infamous. In 1957, Senator Strom Thurmond of South Carolina spoke for 24 hours and 18 minutes to try to block the Civil Rights Act of 1957. He prepared by taking steam baths to dehydrate himself so he would not need the bathroom, and an aide reportedly waited in the cloakroom with a pail. The bill passed about two hours after he finally sat down.
His record stood until 2025, when Senator Cory Booker held the floor for 25 hours and 5 minutes. Others filled the hours their own way: one senator read the District of Columbia phone book aloud, another read bedtime stories.
From the Dutch vrijbuiter, a pirate or freebooter, by way of the Spanish filibustero.
The filibuster is why so much major legislation needs sixty votes in the Senate, not fifty-one. One determined voice, or a small group taking turns, can still bring the chamber to a halt. Whether that protects a minority or paralyzes the majority is the argument that never ends.
