The full text of the speech given by President Barack Hussein Obama in Chicago after he won a second term in office as US President has been broken into its minimal communicative speech acts. This strategy has been used to analyse and understand how the whole speech is consistent with the cooperative maxims of Quality, Quantity, Relation and Manner. Being a corpus-based work the study goes through the Rhetorical Criticism Approach with the Textual Analysis as the method at hand. The resulting interpretation shows that President Obama's speech fascinated and positively affected his listeners' emotions because it was highly consistent with all the four maxims of Cooperation, that is, the speech was cooperative in design. With these results we can confirm that the cooperative quality of a political speech is crucial to the audience's appreciation of the speaker and the value of his public talk.
