Candidates' Ideological Locations,Abstention, and Turnout in U.S. Midterm Senate Elections

Many spatial models of voting suggest that citizens are more likely to abstain when they feel indifferent toward the candidates or alienated from them. In presidential elections, previous research offers evidence that alienation and indifference affect individuals' probabilities of voting. We find evidence that indifference and alienation also affect the decision to vote in midterm Senate elections, a context not previously explored. These individual-level effects imply that candidates' ideological locations should influence aggregate turnout by affecting the proportions of citizens who feel indifferent toward or alienated from the candidates. Our aggregate-level analysis supports this (at least in contests featuring two previous and/or future members of Congress). Our findings underscore the importance of the electoral context for understanding citizen behavior and suggest that elections featuring at least one centrist candidate may be normatively appealing since they stimulate participation.     

Ideology and Representation in the US Senate: Roll Calls v. Constituent Assessments

Most research on representation in the US Congress examines the relationship between the voting behaviour of legislators and citizens' preferences. Using a roll call-based measure (DW-NOMINATE scores) of US Senators' ideologies and citizen assessments of Senators' ideologies (from the American National Election Study: Pooled Senate Election Study 1988, 1990, 1992), we demonstrate that judgements about Senators' responsiveness (the extent to which more liberal/conservative Senators represent more liberal/conservative states) is sensitive to measurement issues. In addition, using citizen assessments, we move beyond responsiveness to examine ‘representativeness’ (the extent to which Senators' ideologies match the average ideologies of their constituents) as a dimension of representation. We conclude that citizen assessments should not be overlooked since representation may ultimately be a phenomenon that rests in the eye of the beholder and since governmental legitimacy itself rests on citizens' attitudes and beliefs.
