Radical campaigner omitted GNP figures for largest economy (7)
I believe the answer is:
america
'radical' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for america that I've seen before include "Ira came from the continent" , "Continent of the Western Hemisphere" , "Curious camera I take to the continent" , "Take care and aim for the continent" , "Land of the free and home of the brave?" .)
