Some thoughts. (And don’t kid yourself — it was entirely killed. Making it quicker for district-but-not-circuit court judges to be confirmed after cloture? Please. That’s “filibuster reform” in the same sense that a lollipop from the bowl on the desk of a doctor’s receptionist is a “cure for cancer.”)
Sadly, the best chance for putting the filibuster on the path to destruction probably remains Republicans during a period of unified government putting their short-term policy interests ahead of the long-term interests of their movement. Their more ideologically unified conference makes this a little more likely.
