Sverigedemokraternas ökade inflytande i kommunvalen 2010, 2014 & 2018 : En kvantitativ studie av hur kommunpolitiken utmanas av interna och externa faktorer i relation till politiskt väljarbeteende och Sverigedemokraternas lokala valframgångar

Sammanfattning: The aim of this paper is to investigate the internal and external supply in relation to citizens’ demand for radical populist parties. To explore how the Sweden Democrats between 2010 and 2018 has developed its party organisation and how this has changed over time. The essay is based on the theory of Cas Mudde which claims demand and supply as a reason and understanding for the increasing growth of radical right parties in Western democracies. The theory divides Sweden Democrats into three different aspects; demand, internal and external supply which explain the stability and increased support for the party. Socio-economic factors such as unemployment, education and level of immigration are significant explanation factors for radical right parties to establish on long term. However, the essay concludes that the internal aspects of the party organisation, in relation to lack of trust for the traditional parties and low party identification, are crucial explanations. The importance of these factors have gradually increased during the years 2010-2018, while the level of significance for socioeconomic factors have decreased.
