Friend or Foe? Testing the Influence of Populism on Democratic Quality in Latin America

This article examines the influence of populism on democratic quality in Latin America. It draws on findings of qualitative work on this question as well as a theoretical framework by Cas Mudde and Cristóbal Rovira Kaltwasser to test whether the assumptions and results of both are applicable in a comparative study. It is expected that populist actors have a negative impact on democratic quality when they are in government, but that they positively influence democratic quality when they are in opposition, where they can function as a corrective. Further, it is expected that these effects vary depending on the level of consolidation. A linear mixed-effects model and data from eighteen Latin American countries in the period 1995–2009 was used to evaluate the hypotheses. Generally, it was found that populist actors in opposition have a large positive influence on democratic quality and that populist actors in government have a negative influence.
