概要	An issue framing experiment manipulates how a political issue is described, emphasizing different considerations, to test how framing shifts opinion. Nelson, Clawson and Oxley's (1997) classic study showed that framing a Klan rally as a free-speech issue versus a public-order issue changed tolerance judgments, and Chong and Druckman (2007) systematized framing theory and the experimental methods used to estimate framing effects.	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.
