The way politicians communicate with the electorateand run electoral campaigns was reshaped by the emergence and
popularization of contemporary social media (SM), such as Facebook, Twitter, and Instagram social networks (SN). Due to
inherent capabilities of SM, such as the large amount of available data accessed in real time, a new research subject has
emerged, focusing on using SM data to predict election outcomes. Despite many studies conducted in the last decade, results are
very controversial, and many times challenged.
