0628 supreme
An exterior view of the U.S. Supreme Court is seen on June 21, 2012 in Washington, D.C. - 

This final note on the way out today: An observation, if you will, about some of what you heard on the program today -- the health care bits, specifically.

The truth is, for all the predictions about how much it's going to cost, how much it's going to save or what's going to happen next -- we just don't know. Nobody does. The American economy is an inherently unruly beast, and when you make structural changes to fully 20 percent of it, you just kind of have to wait and see what happens.
