Multiscreen viewers. The sentiment of messages on Twitter during the electoral debates

This article analyzes the sentiment of messages posted on the social network Twitter during the electoral debates in for the regional elections held in Galicia and the Basque Country in 2020. The aim is to test whether a dominant negative sentiment exists in the messages and whether this varies when the candidate for re-election intervenes -election competition-, whether it differs when parties from the ideological extremes intervene -echo chambers-, and whether the same reaction occurs when the issue at stake affects both electorates equally. It is shown that in the Basque Country it is more important who intervenes -more electoral competi-tion-, while in Galicia the issues are the ones that motivate Twitter conversations.
