ABSTRACT This paper carries out an analysis of the emotions present in the online communication that the communities of users of the social network Twitter perform in the accounts of the candidates during the pre-campaign and electoral campaign for the general elections, in the cases of Spain and Bolivia in 2019. A total of 721,112 replies have been analyzed through the Linguistic Inquiry and Word Count program. The work focuses on deepening the relationships between the positive and negative emotions present in the messages, in the possible relationships that these have with the level of activity and the size of the user community, to determine the existence or not of intra- and inter-case study patterns. The conclusions not only provide empirical evidence regarding the use of this analytical program in the Iberoamerican context, but also open interesting lines of research regarding the profile of user communities and their influence on the definition of emotional communication frameworks.
