The authors examined political candidates' social stereotypes of Mexican immigrants in mainstream media accounts. From those popular themes, they formed semantic differential scales, which they administered to participants (N = 201) with 1 of 4 scenarios describing an illegal immigrant: of Mexican vs. English Canadian descent and with vs. without several parking tickets. Consistent with contemporary theories of prejudice (J. F. Dovidio & S. L. Gaertner, 1996), the participants indicated the greatest agreement with the pejorative themes when the immigrant described was of Mexican descent and had accumulated parking tickets. Psychologically, the parking tickets served as a nonethnic rationale for discriminating against that ethnic group. The authors discuss the social and public policy implications of Mexican immigration as a political phenomenon.
