This article is a follow-up to an article published in the American Behavioral Scientist in 2017, titled “Shaping public opinion for confrontation: Catalan independence claims as represented in Spanish, Catalan, Valencian, and Basque Editorials.” At that time, our study was based on opinions expressed in mainstream newspaper editorials during two significant events in Catalonia’s recent history: the demonstration against the Spanish Constitutional Court ruling on the Statute of Autonomy of Catalonia of July 10, 2010, and the mass pro-independence demonstration held on September 11, 2012. The research sought to compare the press reports published in Catalonia, Valencia, and the Basque Country with those from the rest of Spain (primarily Madrid). This study applies the same methodology to analyze editorial pieces published during the campaign prior to the Catalan parliamentary elections on December 21, 2017. This date was historically significant for Catalonia because for the first time since the restoration of democracy following the Franco regime, the Spanish state had intervened in Catalonia’s self-rule by using Article 155 of the Spanish constitution to call snap elections. At the time, the lead candidates for the pro-independence parties were Oriol Junqueras (Republican Left of Catalonia) and Carles Puigdemont (Together for Catalonia), the former in prison and the latter abroad (or in “exile,” according to secessionists). In light of the opposing opinions and perspectives, we believe it is worth analyzing and comparing mainstream editorials from Catalonia (Barcelona) and Spain (Madrid) once again, to ascertain the dominant narratives used in both to explain the Catalan and Spanish position and frame of reference. We have extended the scope to include mainstream online as well as printed media with a view to achieving a better understanding and providing a wider overview of the public agenda and debate at that time.
