The United States with its presidents stepping into power from either the Democratic or Republican parties influences global affairs in one way or another. These two main political parties have long been struggling for power and the significance of tapping into the ideological inclinations of the two parties underscores scholars’,accountability toward raising the critical language awareness of the public which could be an initial step toward a change for the better. The presidential inaugural speeches, due to their programmatic and strategic nature, are of significance to researchers. This study employed van Dijk’, s (2006b) socio-cognitive framework where he defined two levels of analyses for a political discourse including the micro-level and macro-level text analyses. The former included 25 discursive devices such as polarization, generalization, hyperbole, etc. The latter drew on the dichotomy of ‘, positive self-representation’,and ‘, negative other-representation’, . In the present study, the linguistic features in 16 inaugural speeches delivered by American Democratic and Republican presidents from 1961 to 2017 were examined at both levels. The overall data analysis revealed that Democrats employed ‘, norm expression’,and ‘, presupposition’,significantly more than Republicans, while Republicans made more use of ‘, categorization’, , ‘, lexicalization’, , and ‘, populism’, . The macro-level comparison of the two parties indicated that both Democrats and Republicans resorted to using ‘, positive self-representation’,significantly more than ‘, negative other-representation’,while the deployment of ‘, negative other-representation’,by Republicans was significantly more than that by Democrats. The findings of this study have some implications for English for political purposes, political studies, as well as attempts in discourse studies.
