[TPM SLIDESHOW: Block That Bill: A History Of The Filibuster]
This news follows National Journal's report that all returning Democratic Senators had signed a letter to Reid, spearheaded by Sen. Tom Udall (D-NM), urging he should consider taking action:
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.
At the very least, it looks like Dems are gearing up to even talk about the topic in a serious way.
