It is absolutely true that yesterday's victory in forcing Harry Reid to pull the FISA bill from the Senate floor is temporary. Allies of the administration and lawbreaking telecoms will spend the next several weeks plotting to overcome the obstacles thrown in their path yesterday and, like a weed that has been cut but not uprooted, will return in January to try again.

Opponents of telecom amnesty and warrantless surveillance ought to and likely will use that time, too, to strengthen the opposition and improve the strategy. There will be ample time for all of that. But yesterday's victory, while limited, is still very significant in several key respects, particularly in understanding how and why it happened -- i.e. the source of the successful opposition -- and it is worth taking a step back to chronicle what took place.
