In recent years scholars of American politics have paid a great attention to party elites' ideological polarization and the mass reactions to the changed political environment. Applying a novel empirical strategy, this study attempts to contribute to this body of literature examining the mass consequences of party elites' ideological polarization. More specifically, using the cumulative ANES (American National Election Study) survey , this paper examines how ordinary citizens have responded to the polarizing political environment in terms of changes in their ideological positions and levels of political awareness. In particular, assuming that mass effects of the polarized politics could be potentially heterogeneous in these two dimensions depending on citizens' existing positions in the distribution of dependent variables (i.e., ideological positions and political awareness), this study utilizes a quantile regression model to account for differential responses of citizen strata in addition to the ordinary regression analyses of conditional mean effect for the general electorate. Empirical findings here suggest that the general electorate not only becomes to perceive more ideological differences between the two parties, but they also tend to adopt more extreme positions on the ideological self-placement. In addition, this study demonstrates that the mass effects of growing congressional polarization are quite consistent across different strata of the electorate rather than being disproportionate. This result contrasts sharply with the claim of who argue that mass polarization is largely limited to the small subset of population with stronger ideological orientation.
