Congressional responsiveness to presidential popularity: The electoral context

A number of recent studies have reported that the influence of the president's public approval rating on congressional support is not substantial. We hypothesize that this unexpected finding might be the result of the inappropriate application of an approval-driven model of legislative voting to the entire Congress. Specifically, we argue that members from certain kinds of electoral contexts—constituencies where the president's, or their own, electoral standing is in doubt—should be especially likely to vary their support for the president with changes in his approval rating. Although the patterns of presidential support scores between 1977 and 1991 do not confirm our specific hypotheses, they do suggest that the electoral context from which a legislator emerges does shape his or her responsiveness to changes in national presidential approval.
