Based on the results of the POPREBEL project I will argue that the most complete explanations of the rise of right-wing populism need to look for explanatory factors in economy, culture, politics, and social conditions, theorize the complex interactions of supply and demand, and reconstruct the iterative logic of their mutual influence. The most promising theoretical frame seems to be offered by a mix of the approach I once called contextual holism, historical institutionalism, and a supply-demand theory of cultural causation.
