“…Facebook, Instagram and Twitter, among others, are nowadays means for politicians to publish and share their messages (López-López & Vásquez-González, 2018), as well as to interact with citizens without the mediation of media outlets. In particular, politicians have adopted Twitter as one of the main tools for effectively interact in real-time with their audiences (Vergeer & Hermans, 2013;Graham, Jackson & Broersma, 2014), and citizens have also adopted the microblogging platform as a way for them to express their political attitudes and preferences (Amaral, Zamora, Grandío & Noguera, 2016;Hosch-Dayican, Amrit, Aarts & Dassen, 2016;Said-Hung, Prati & Cancino-Borbón, 2017;Cifuentes & Pino, 2018). Since social networks interactions are considered to follow a filter buble logic (Pariser, 2012) and can thus be easily used to reveal users' preferences, a considerable part of the research in Twitter has been focused on the uncovering of latent attributes of the users, in particular their political preferences (Guerrero-Solé, Corominas-Murtra & López-González, 2014;Fang, Habel, Ounis & MacDonald, 2019), or their political activity online (Bruns & Highfield, 2013;Gelado-Marcos, Rubira-García, & Navío-Navarro, 2019).…”
