“…that to speak of "public opinion" at all may be a misnomer, and therefore to presume that public officials can sensibly respond to or manipulate such a slippery entity is a mistake. However, in Canada, Europe and the United States, there is ample evidence that despite these legitimate methodological and theoretical critiques, when individual opinions are aggregated and tracked over time, collective opinion looks far more stable and reasonable than individual responses to survey questions, and demonstrates consistent correlations with policy and changes in the environment~Bélanger and Petry, 2002;Feld and Groffman, 1988;Isernia et al, 2002;Johnston, 1986;Page and Shapiro, 1992!. Another reason as to why policy might diverge with opinion as measured by polls is that, although elected officials may try to respond to public opinion, they do not think that polls accurately represent the real state of public opinion. They may therefore rely on other indicators or interpretations of public opinion that they find more useful than polls to assess where majority opinion stands on an issue.…”
