The Reputational Premium presents a new theory of party identification, the central concept in the study of voting. Challenging the traditional idea that voters identify with a political party out of blind emotional attachment, this pioneering book explains why party identification in contemporary American politics enables voters to make coherent policy choices. Standard approaches to the study of policy-based voting hold that voters choose based on the policy positions of the two candidates competing for their support. This study demonstrates that candidates can get a premium.
