A filibuster, while it would be great, is not needed. All ONE senator (Feingold?) needs to do is to withdraw unanimous consent from everything, and the senate will be forced to a crawl to follow the full, lengthy, archaic rules of the Senate on everything. (See entry from Wikepedia in extended copy below the fold)
The Democratic Senators should filibuster, it is the right thing to do. If they don't want to do the right thing for ANY reason, revoke unanimous consent and run out the clock. Call for quorum every 10 minutes, make privileged motions for a closed session. Do WHATEVER it takes! They could USE the slogan Let the voters decide! This will completely nationalize the election to STOP TORTURE. Whatever is done, the trampling of our constitutional rights and the condoning of the barbarism of torture MUST NOT be written into our laws.
