Many people share your sentiment, that the GOP has to invoke some process whereby the Senate is in session around the clock. The term "filibuster" is bandied about and there have even been protracted discussions about the definition (i.e., some taking and arguing "the Senate is in a filibuster," and other arguing "no it isn't, not until . . . ."). I find the "filibuster definition" discussion boring and tiresome.
What I would like to hear is a more particular description of the process, under Senate rules or otherwise, that will result in 24/7 Senate activity. We can speculate in that context of whether that action will result in the confirmation of Estrada, how it will affect the politial landscape for GOP and DEM parties, etc.
