According to many observers, contemporary politicians too often are being swayed by the issues of the day. Elected representatives are supposed to permanently monitor public opinion in general and opinion polls in particular and to act accordingly. An analysis of in-depth interviews with Dutch MPs and a content analysis of an important, long-lasting debate in Dutch Parliament indicates, however, that this popular claim is a misconception. Elected representatives disagree on the content and manifestations of ‘public opinion’ and seldom take it into consideration in their role as representatives. Moreover, public opinion is taken seriously only if it is well-considered and based on substantive knowledge and conclusive arguments.
