How does a filibuster kill a bill?

A filibuster allows a senator to extend debate on a bill, effectively delaying or blocking its passage by preventing a vote. It requires a supermajority of 60 votes in the Senate to invoke cloture and end the debate, which can be difficult to achieve. As a result, if the majority party cannot muster enough votes to overcome the filibuster, the bill may ultimately be sidelined or defeated. This tactic is often used as a strategic tool to stall legislation that lacks broad support.
