“…In this contribution, we focus on the influence of debates on political attitudes towards candidates and issues, the impact of which is heavily disputed in the literature. While a meta-analysis by Benoit, Hansen, and Verser (2003) indicates that viewing televised debates can affect issue preferences and attitudes respondents hold towards the candidates (see also, e.g., Abramowitz, 1978;Geer, 1988;Lanoue & Schrott, 1989a, 1989b, most studies on debates in the U.S. suggest that debates reinforce already existing attitudes rather than transforming them (see, e.g., Chaffee, 1978;Hagner & Rieselbach, 1978;Katz & Feldman, 1962;Kraus, 2000;McKinney & Carlin, 2004). These findings are in line with the results from classical campaign research that the reinforcement of attitudes is the most important campaign effect.…”
