Linguistically, political discourses have generally been discussed within qualitative approaches (e.g., Blackledge, 2005; Chilton, 2004; Chomsky, 2004; van Dijk, 2005; Wodak, 2002). This paper presents tools to design a quantitative research relating political speech with sociolinguistic variables. Notions such as Accommodation Theory (Giles & Powesland, 1997), Audience Design (Bell, 1997), and Identity (Fairclough, 2003; Mendoza-Denton, 2004) shape the rhetorical performance of politicians and explain the importance of sociolinguistic variables within political discourse. Once those realities are correlated, I define social variables (socioeconomic status SEC [Labov, 2001]) and linguistic variables (morphosyntactic, lexical, and pragmatics variables [Schilling-Estes, 2004], address forms [Ervin-Tripp, 1972], vocabulary [Fairclough, 2003]) to develop a sociolinguistic study on a corpus of political discourses. Finally, linguistic variants are proposed and put into practice analyzing Latino American politicians to hypothesize a possible correlation between left-wing politicians and linguistic choices.
