Why was the Filibuster overturned? [Open Answer]

Once the Filibuster has been overturned, what was the issue that caused the Filibuster to be eliminated? Assuming that a bill failed to reach the requisite 60 votes needed to pass the Senate floor, this will Resolve to whatever the core content of the bill includes. If the Filibuster is overturned not in relation to a single bill’s failure, this will Resolve to the first major bill passed without a Filibuster with fewer than 60 votes (assumed to be the Majority leader’s top priority). There is a chance that this could Resolve to multiple options (at a partial percent), if a singular bill addresses multiple issues. Or if two bills are passed directly back-to-back, this will need to be in pretty quick succession, not across days/weeks. Each issue can be assumed to be either pro/anti the issue (i.e. Abortion would be codifying Roe v. Wade, or a national Abortion ban). Feel free to add anything missing, but I will N/A any broad generalizations (e.g. “a culture war issue”, “LGBTQ issues”). I won’t be betting here, as this could be an objective call. Market will extend as needed. See a “which party will overturn the Filibuster” accompanying market: (https://manifold.markets/embed/mattyb/the-republicans-will-be-the-party-t)
