Most formal models of valence competition add a single, separable andunweighted component to the standard one-dimensional utility function ofvoters. This article presents the results of a conjoint analysis experimentin which respondents were asked to choose between two candidates whoseprofiles vary along five attributes. Four of these traits behave likevalence or policy issues as expected, but one, which has been employed inrecent formal and empirical works, does not. Moreover, policy and valenceare not separable. They interact at least in some cases, taking a competencyform whereby the marginal impact of valence on voters’ choice is conditionalon candidates’ policies. This result lends support to recent studies thathave found more extensive valence voting under ideological convergence.Finally, policy trumps valence in awkward choices. Respondents even prefercorrupt candidates with similar policy views to honest ones with differentopinions, despite integrity being declared the most important attribute.
