Jim: re: initiative, recall and referendum at the Federal level.  You're quite right.  While there is some effort to establish the ability to have a "national" initiative process, it is not in place at this time.  I was incorrect in my statement.

At the State level, Oregon has included them in the Constitution.  Oddly enough, Oregon is the only State which doesn't have an impeachment process to remove State officials.  We all became aware of that with the Kitzhaber debacle.  

I appreciate your correction.  regards, Gary
