Drawing on overarching methodological frameworks of Hallidayan grammatical metaphor, Fairclough’s perspective on critical discourse analysis and rhetoric, this study attempts to posit a novel, integrated and practical approach to political, the media, advertisement and other discourses. To this end and based on the proposed approach, it aims to critically and eclectically exemplify and dissect three speeches delivered by Mr. Barack Obama, former president of the US, to first manifest the integrated approach practicality and adeptness through analysis; then by virtue of analysis to unveil how language is manipulated and distorted by orators in order to convey seamlessly intended messages and political creeds to the audience. Surveying recent annals of literature, to date no one has conducted an integrated study applying these disciplines in an individual paper and this study as a trial one can be useful for upcoming research. The analysis depicts practicality and efficiency of the integrated approach and displays that the speeches abound with nominalizations, modal verbs, parallelisms and antitheses. Furthermore, there are some three-part listing, the use of passivization, quotations and modality metaphors. Therefore, a tendency to utilize more nominalizations, parallelism and other devices by the speaker can be a fundamental reason for making his political language more powerful, impressive, persuasive and ambiguous as well.
