That is my understanding as well. Under the current rules, all the demonRATs have to to do filibuster is SAY that they are going to filibuster. If the Republicans can't get 60% to override then they have to move on.
What I want to know is if the Republicans have the power to change this stupid rule back to how it used to be. If the demonRATs want to filibuster, make them really filibuster. Make one of them hold the floor for 24/7 reading the phone book on CSPAN until he drops. Then vote.
