Party identification and issue preferences are central explanatory factorsin many voting choice models. Their effects on party preferences are usuallyunderstood to be additive. That is, issue preferences’ impact on partyutilities is assumed to be the same among both party identifiers andnonidentifiers. This article suggests an alternative model in which partyidentification moderates the impact of issues on the vote. The impact ofissue preferences on party utilities should be weaker among voters whoidentify with a party. This hypothesis is tested using data from four recentDutch election studies. The results show that identifying with a partysubstantially weakens the issue preference effect on party evaluations,particularly for the party with which a voter identifies.
