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
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.
Section 3
The minority party loses its primary leverage
The filibuster gives the minority party the ability to block legislation without holding a majority. Eliminating it would shift power decisively to whoever controls 51 seats, reducing the minority to procedural delay tactics rather than substantive blocking power.
Section 4
Long-term institutional consequences
Critics argue that eliminating the filibuster would make American law more volatile, as each new majority could undo the previous one's work. Supporters argue that the current system creates permanent gridlock and allows a minority to prevent majoritarian governance.
