Metaphor, Morality, and Politics Liberals do not understand what unifies their own worldview and so are helpless to deal effectively with conservatism. Not only is there no unified liberal political structure, but there is no overall effective liberal rhetoric to counter the carefully constructed conservative rhetoric. Where conservatives have carefully coined terms and images and repeated them until they have entered the popular lexicon, liberals have not done the same. Liberals need to go beyond coalitions of interest groups to consciously construct a unified language and imagery to convey their worldview. This will not be easy, and they are 30 years behind.
