What happens if the U.S. Senate eliminates the filibuster?
The filibuster is a Senate procedural tool that effectively requires 60 votes to advance most legislation. Eliminating it would transform the Senate from a supermajority institution to a simple-majority body.

Briefing Sections
This briefing covers 4 sections explaining the political structures, legal frameworks, and real-world dynamics behind this process.
Section 1
The Senate changes its own rules
The filibuster exists as a Senate rule, not a constitutional requirement. The Senate can change its rules by a simple majority vote through the so-called nuclear option, as it has already done for executive nominations (2013) and Supreme Court confirmations (2017).
Section 2
Legislation would move on simple majorities
Without the filibuster, any bill that could pass the House and win 51 Senate votes (or 50 plus the vice president's tie-breaking vote) could become law. This would dramatically increase the pace and scope of legislation, especially in the first two years of a new presidency.
