1) While it's a valid question, it's even more valid IMHO if directed at the media.
2) It's my understanding that the GOP is the party that would ultimately be worn out during a real filibuster. The Dems could schedule just a handful of folks to be in the Chamber, while a solid portion of the Pubbies would need to be there in the event a voting opportunity arose.
Plus, a real filibuster holds up all other work, including a tax cut. What do you think the American public cares more about - the economy or judicial nominees? So which party ultimately loses in the end?
