Abstract: This study examines the role of negative (anger, fear) and positive emotions in addition to political attitudes (political trust, populist attitudes, external political efficacy) as key determinants of voting behaviour. We rely on the RepResent voter survey conducted in 2019 in Belgium (n = 3236) allowing us to assess the relationship between emotions, political attitudes, and the vote for radical right (VB, PP) and radical left parties (PTB-PVDA). Findings indicate that anger is significantly and positively related to voting for radical left and right parties, while controlling for key political attitudes and issue positions. Fear and positive emotions are not significantly more related to voting for radical parties than for other parties. The results suggest that anger should be more systematically integrated in electoral research. These findings call for further analysis on the causal mechanism linking emotions and voting behaviour, and the (in)direct effects of emotions on voting.
