Since September 11, 2001, anti-Americanism has emerged as an important issue in international politics. In democratic election campaigns, anti-Americanism should be an attractive issue where it is expected to have a favorable impact on key swing vote constituencies. Anti-Americanism has certain inherent ideological appeals and more varied historically-based attractions. Anti-Americanism should be least attractive where countries continue to rely on U.S. security guarantees. South Korea's December 2002 presidential election, in which winner Roh Moo-hyun openly sympathized with anti-American demonstrators, appears to contradict this expectation. Yet closer analysis of individual-level polling data shows that anti-Americanism was, both statistically and substantively, much less significant than alternative campaign issues. By activating the numerous voters hostile to the North Korean regime, anti-Americanism actually hurt the victor's electoral chances. The approach appears useful in understanding why anti-Americanism is a more prominent ideology and electoral issue in some regions, such as Western Europe and Latin America, and a less prominent one in others, for example Eastern Europe, East Asia, and Oceania.
