So let's talk about filibusters, obstruction, and the Senate in light of the 11th-hour deal on Tuesday that averted a midstream rules change by majority Democrats and a threatened Defcon I by minority Republicans over blockage of a slew of executive nominees.
First, a broader point. The United States Senate is unlike any other parliamentary body in the world. It has rules like the others, it has structure like the others, it has partisanship like the others. But it is less reliant on strict rules and less structured than any others. The Senate runs on unanimous consent for almost everything it does, and it's more of a delicate organism than a well-oiled machine. For the Senate to function, it needs comity, and to function well, it needs all of its members -- all of them -- to cooperate.
The rank-and-file members of most parliamentary bodies are cogs in the machine; some are bigger and more powerful than others, but individual cranks, lunatics, obdurate asses, showboaters, and recalcitrants become minor annoyances who can largely be ignored or steamrolled.
The individual members of the Senate are not so easily dealt with. Those who want to be (to use the more polite phrase) skunks at the garden party can divert and block the Senate in many ways, even if a majority of members and even leaders object. By denying unanimous consent, taking and holding the floor, turning some of the looser rules on their heads, and, especially, stepping in at critical times at the end of sessions to block action when time is precious, individual senators can wreak havoc -- and, sometimes, get their own way.
If the Senate is to play its part in solving problems, this dynamic requires that senators find ways to work together, to keep their partisan bents from spilling over, to limit the damage that can come when many individual senators decide to bollix up the works. That means the norms of the Senate are more important than the rules.
And that is where the Senate has broken down in an unprecedented way over the past six years or so. The rule of the Senate that has regulated debate and provided for a way -- cloture -- to stop debate with a 60-vote threshold is Rule XXII. It was last amended in 1975. It worked pretty well for 30 years. Of course, there were times when majority leaders were frustrated by minority actions -- more often by rogue individuals than minority leaders -- and the roles did switch when majorities, and presidents, changed. The rule did not change in 2005, when Democrats in the Senate blocked confirmation for a series of President Bush's Appeals Court nominees, leading to Majority Leader Bill Frist's threat to change the rules by majority vote, and a last-minute compromise by a "gang" of 14 senators, seven from each party, to enable most of those nominees to be approved and the Senate to resume normalcy -- which did not last even two years.
And the rule did not change in 2007, when Democrats recaptured the Senate, or when Barack Obama became president in January 2009. But the norms did. As anybody paying the slightest attention over the past few weeks knows, we have gone from the era when Senate Majority Leader Lyndon Johnson faced one filibuster during his tenure to Majority Leader Harry Reid facing 400 cloture votes on issues and nominations to try to end debate and move to action.
