Obviously, I’m no big McCaskill fan, and she’s going to have to do more to get my enthusiasm (and shoeleather) come campaign season. But after her tough votes on the DREAM Act and on DADT repeal, she’s following up with something historic: filibuster reform.

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.

“There need to be changes to the rules to allow filibusters to be conducted by people who actually want to block legislation instead of people being able to quietly say ‘I object’ and go home,” said Sen. Claire McCaskill, D-Mo.

Good on ya, Claire. Get it done.
