The Mediated Horserace: Campaign Polls and Poll Reporting

Although "horserace journalism" is thought to be central to contemporary election news coverage and has generated a great deal of criticism, there is no general model of the nature and dynamics of horserace journalism or "poll reporting." This paper proposes and empirically evaluates such a model. The model builds on and extends John Zaller's "theory of media politics" to consider specifically what citizens demand from polls and what journalists supply. Aside from the generic motivations of politicians, citizens and journalists, the model emphasizes the unique features of polls as objects of news coverage. The paper finds considerable support for the model in an analysis of newspaper coverage of horserace polls (that is, vote intention polls) in the Canadian general election of 2006. Our findings from this one case have potentially broad implications for our understanding of the relationship between polls and electoral democracy both empirically and normatively.
