What strategies can be used to kill a bill?
The senator can employ various strategies to kill a bill opposed by constituents. Options include having the Rules Committee block scheduling, filibustering to delay or prevent a vote, proposing a killer amendment to create dissent, or refusing unanimous consent to prevent the bill's progress.
Each tactic aims to impede the legislative process, making it challenging for the bill to advance and ultimately thwarting its passage.
