Summary	A candidate evaluation model represents how voters form overall assessments of political candidates as a latent function of perceived traits (competence, leadership, integrity, empathy), partisanship, issue proximity, and affect. It spans the trait-based factor models of Kinder et al. (1980) and the online-processing tally model of Lodge, Steenbergen and Brau (1995), which describes evaluation as a running summary updated as information arrives.	The Partisan Identity Scale measures strength and direction of psychological attachment to a political party, encompassing both party preference and emotional party identification. Foundational since Campbell et al.'s American Voter (1960), the measure distinguishes party affiliation (which party one is registered with) from party identification (psychological identity with a party as a social group). Partisan identity is among the strongest predictors of voting behavior, political attitudes, and interpretation of political information, functioning as a 'perceptual filter' through which voters process news.
