Last month, every member of the Senate Democratic caucus signed a letter signalling support for reforms that would end anonymous holds and force the minority to actually mount a continuous debate if it wanted to block a bill, rather than require a supermajority vote even to begin a debate:
All Democratic senators returning next year have signed a letter to Senate Majority Leader Harry Reid, D-Nev., urging him to consider action to change long-sacrosanct filibuster rules.
The letter, delivered this week, expresses general frustration with what Democrats consider unprecedented obstruction and asks Reid to take steps to end those abuses. While it does not urge a specific solution, Democrats said it demonstrates increased backing in the majority for a proposal, championed by Sen. Tom Udall, D-N.M., and others, to weaken the minority’s ability to tie the Senate calendar into parliamentary knots.
Among the chief revisions that Democrats say will likely be offered: Senators could not initiate a filibuster of a bill before it reaches the floor unless they first muster 40 votes for it, and they would have to remain on the floor to sustain it. That is a change from current rules, which require the majority leader to file a cloture motion to overcome an anonymous objection to a motion to proceed, and then wait 30 hours for a vote on it.
What happened next? Let's see. First, Republican critics attacked the reforms for doing away with the supermajority requirement even though (sadly) they did no such thing. Then the few conservatives who actually understood what the reforms would do (which, again, was not -- NOT, Senator Alexander -- prevent the minority from obstructing legislation) admitted they actually made a lot of sense.
And, now, of course, the denouement -- Senate Democrats fold like a cheap suit:
