Satellite campaign is defined as campaigns which are not initiated by official actors--such as candidates or political parties. It is often initiated by citizens who support certain candidates or political parties through unofficial channels, such as social media. Being unofficial and under less scrutiny, satellite campaigns have the risk of being ridden with populist messages and misinformation. Emotions tend to present in both populist message and misinformation because of their ability to make the messages feel personal and more compelling. This paper aims to unveil how emotions are employed in satellite campaigning especially within the context of populist messages and misinformation. Towards that end, social media data were analysed using sentiment analysis to identify the emotions used in social media posts by satellite campaigners. Additionally, network analysis was also used to examine how these emotion-laden posts are distributed in social media networks in Indonesia. The results show that negative and positive emotions are prevalent in election-related social media posts. Their use is dictated by the types of posts in question—positive ones are more prevalent in posts made by satellite campaigner who initiate the conversation, while negative ones are in posts responding to posts made by other satellite campaigner. Interestingly, both positive and negative emotions appear in misinformation posts, each contributing uniquely to make the misinformation more compelling. This research will contribute to further the understanding of how social media can affect the electoral politics especially in the context of emotional contents. This research will also provide insights into how emotionally charged content influences voter behaviours, thereby informing strategies for combating misinformation in digital political landscapes.
