This article, by employing voting simulations in a survey of party activists, examines responses to a woman's claim to party office on the basis of her sex. The degree of acceptance of this claim or the willingness to grant what is called social representation, is contrasted with the respondents' inclinations to select candidates favorable to women's rights, or the willingness to grant what is called opinion representation. Variations in responses to the two simulations are analyzed in terms of attitudes toward gender roles, government intervention and the legitimacy of groups in the political process. Voting in the simulation involving opinion representation can best be understood in terms of the respondent's attitude toward government intervention, while the simulation involving social representation activates the attitude toward groups. Discussion of the findings focuses on the dilemma of group claims for minority representation in a liberal democratic context and the need for better understanding of attitudes toward groups among political elites.
