"All of this is a choice. Every Senate rule can be changed by a simple majority vote. A simple majority could end or reform the filibuster — as we saw when Democrats ended it for most executive branch nominations and most judicial nominations in 2013, and when Republicans ended it for Supreme Court nominees in 2017."
This is a good summary of the problems with using budget reconciliation to pass legislation. Democrats should kill the filibuster. Kilibuster.
