The aim of the article is to study the model of symbolic interactionism by the American sociologist Herbert Blumer and to identify the analytical elements that are most applicable to the political analysis of internet communications. The authors used the hermeneutic approach, including the identification of central premises in Blumer's model as well as an additional interpretation of such premises. Quantitative content analysis was used as an auxiliary methodological optics. The analysis demonstrated that the analytical tools of symbolic interactionism from the Chicago School (definitive and sensitizing concepts, exploration and inspection, etc.) can be effectively tailored and used for current research of internet communications in applied political science. The authors conclude that identifying the transaction process is the most important result of applying Blumer’s symbolic interactionism model to a study of social media communities by a political scientist. It is demonstrated that the conditions of social media require investigating the mechanism of behavior adaptation by each individual to the behavior of others. This gives an insight into the mechanism by which social life and the political regime are streamlined and stabilized.
