States of the Union: Much promised, little achieved

From the New York Times, February 13, 2013:

The Times had this graphic on their web page showing how little of what presidents propose in State of the Union speeches actually gets put into action.  If you focus on the "fully successful" line (because "partly successful" seems pretty vague), it seems that the average is about 30% or a little less.  LBJ seems to be an outlier, and presidents working with a Congress of the same party are somewhat more effective, but not as much as you might think.
