Agenda Setting in Congressional Elections: The Impact of Issues and Campaigns on Voting Behavior

Do issues matter? This article extends recent research on issue voting and campaign agenda-setting to voting decisions in congressional elections. We use a unique data set that includes information from a survey of candidates and campaign aides who competed in the 1998 House elections and a survey of individuals who voted in them. The study assesses the impact of campaign-specific variables on citizens’ voting decisions, while controlling for relevant attitudinal and demographic factors. We find that when a candidate and voter agree on what is the most important issue in the election, the voter is more likely to vote for that candidate if that candidate’s party “owns” the issue. The effects of shared issue priorities are especially strong for independent voters.
