Issue Voting Under Uncertainty: An Empirical Test

Enelow and Hinich (1981) proposed a simple model of issue voting for the case in which voters are uncertain about candidates' issue positions. This paper adds an equally simple model of survey responses for issue placement questions that makes it possible to estimate respondents' uncertainty indirectly from existing National Election Study (NES) data. An empirical test of Enelow and Hinich's model based on voting behavior in the 1980 presidential election indicates that voters dislike uncertainty, as suggested by the model. Indeed, uncertainty about candidates' issue positions appears to have been sufficiently pervasive and important to rival issue distances as a determinant of electoral choices.
