Vasu analyzes the attitudes of a national sample of both public and private planners, using a questionnaire he devised and administered, and contrasts the results with a nationwide sample of the American public. He finds that planners are a distinct interest group with ideological orientations, political party affiliations, and political participation that differ significantly from those of the American public.
