The story
Blend of Nixon + economics, equivalent to Nixon + -nomics. Coined in a speech of the same title by Walter Heller in October 1969. This is believed to be the first such term coined by blending a president's surname with the word "economics." http://query.nytimes.com/gst/fullpage.html?res=9E0CEEDB153AF932A35752C1A964958260 Similar blends have been used to describe the economic policies of all subsequent US presidents, though Fordonomics is rare.
