Grassley's admission that privatization probably won't happen -- indeed, that no bill is likely to move forward -- drives that stake nice and deep into the privateers' heart. This is like Moynihan's reluctance to push Clinton's health care bill and his public disparagement of its chances, the combination of which did much to kill the plan. Go Grassley!
Update: The reason this is such a big deal, which I forgot to mention, is that Grassley, as chair of the Finance Committee, is charged with writing the bill and bringing it to the floor. He's the guy. And the guy thinks there'll be no bill.
