Back in the LBJ era, Democrat Senator Mike Mansfield came up with the idea of "TWO TRACKING" to allow the senate to keep doing business on an alternate track after a filibuster was announced. In typical government double talk it meant (and still does) that you can say you're doing a filibuster to stall a vote without really doing anything.
If these egg sucking dogs were true to their disgusting values they would just have a big over stuffed 'in box' on the dais that they could pile full of items, resolutions and bills someone doesn't like. Then just one senator could stall or kill anything like one stinking liberal can do with a school play or nativity scene.
Yes. They are just too damn lazy now to do the actual ‘work’ of a filibuster. It is all horseshit bravado threat.
