This paper focuses on the analysis of the discourse formed by the ordinary citizens discussing news on the Internet social networks. Conceptualizing the theory of the variability of interpretation, the authors study political discourse emerging on Runet, with the aim of identifying the determinants of variation. The empirical base is the news published on “Newsland.com”, which cover the 2014 and 2018 Olympic Games. These mediated events do not aim to cover political issues. However, they stimulate the interpretation activity of the addressees who tend to discuss political background of the sports events as well as to disclose major problems in society. As the analysis shows, there are two groups of factors influencing the interpretation activity of the participants of political discussions in the Russian Internet: objective, determined by the text as a sign, and subjective, determined by the interpreter’s attitude towards the mediated event. The authors argue that the semantic and pragmatic presumptions, as well as the implicatures of the media news are among the mechanisms of interpretative variation. Additionally, the paper shows a significant role in the interpretation of such a subjective category as anticipation or expectation, which also refers to the implicatures. This factor largely determines the interpreter's point of view on the information presented in the article. The methodological pathos of the article is to assert the possibility of identifying, describing and modeling internal and deep categories of everyday political discourse based on the analysis of its external manifestations.
