I heard Rush speak about their tactics the other day. The endless amendments are introduced in order to expose weakness in dem support. Nelson, Lieberman, and others have shown their own lines in the sand. It stands to reason that others will come forth with other demands to if nothing else get the same amount of attention($$$) that they are commanding.
Even more interesting is that while Ralphie was demanding a Red Rider (very specific) BB gun, he now seems to be content with a generic cap pistol instead. His liberal friends are quite upset with him over this, but he is not responding to them. Why? I have no clue.
