The existence of the media and ideology is akin to two sides of a coin. This existence is characterized by interrelatedness and mutual influence. During the Presidential Election of 2019, partisanship became a prominent issue. The media was regarded as being partisan and supportive of the incumbent. Similar case was observed during the Presidential Election of 2014 where the author identified the partisanship of the daily the Jakarta Post toward one of the presidential candidates. This stance is reflected on the editorial of the Jakarta Post entitled Endorsing Jokowi. Through this editorial, the Jakarta Post established itself as the only daily that openly threw its support for one particular presidential candidate. The analysis of this research is based on the Critical Discourse Analysis developed primarily by Teun Van Dijk in order to identify the reasons and means employed by the Jakarta Post to demonstrate its partisanship. The choice of theme, outline, diction, vocabulary and sentences used in this editorial reflects the attempt to marginalize, trivialize and accost the other candidate. In addition, the editorial contributed in providing insight on the candidate and the unfolding event. The research also identified the ideology espoused by the Jakarta Post which included pluralism, human rights, civil society and Reformasi which influenced their stance toward partisanship in this daily. Two events that took place during the campaign, which include the bestowal of the title Islamic Commander in Chief and the proliferation of the use of memes as the form of people’s political expression are observed as the social context that spurred the publication of such editorial.
