In democracy that focuses on the individual's participation in the social system, the individual constitutes the direct target audience of politicians who are struggling for power with their citizen identity. Social media is also seen as the most up-to-date communication environment where the leader can directly, instantly and directly be able to / interact with her audience and establish a community system of her own. In the research, an answer to the questions of “Do political leaders have an open and direct intervention to democracy on social media?” and “How are leaders communicating with the masses in a critical and emotional election?" have been sought. For this, the 2020 US Presidential Election, the consequences of which will affect world politics, has been discussed. The process is set in a time frame with the agenda regarding before-sequence and after. Another important issue is that it is the highest turnout election in US history in the last 120 years; therefore, it points out that the level of expectations and feelings attributed to it is high. In this background and framework, examples were taken from leaders’ tweets; these leaders are at the point of representing the agenda and emotional intensity at the highest level in influencing the masses. As a result, it has been observed that Joe Biden was running the process in a rather flat, cool-blooded, election and Donald Trump-oriented manner, while Trump was an emotional leader acting with his audience in real life and social media with his actions and discourses and that he intervenes directly and openly to democracy in accordance with his leadership and aims, using communication (discourse and emotions) to activate the masses. 9.121 tweets have been obtained and analysed in total using RStudio) programming language. The tweets discussed were subjected to content and sentiment analysis using text mining methods. It is a sign of an era in which the legitimacy of governments and elections in politics can be debated constantly.
