Senate filibuster rule has created a graveyard of bills over the years. The Democrats might alter it. American lawmakers are in the throes of a heated debate about one fundamental rule change that would shift so much of the country’s politics. What happens next to the Senate’s decades-old filibuster rule could not only decide Joe Biden’s presidential legacy but the fate of a slew of bills that have been stalled for years. It’s the rule that requires 60 per cent of senators to agree to even hold a vote on a bill, making it a silent legislative killer over the years that has created a graveyard of bills. Gun control, climate change, immigration reform, electoral reform, statehood for Washington, D.C., Medicare access — bills addressing all these issues could hinge on one procedural choice.
