The 2008 Great Recession has produced changes in the electoral evolution of radical left parties in Europe. The radical left has experienced a modest growth that has reversed previous electoral declines. However, the electoral support for radical left parties has been unequal across Europe and only in a few cases they have been able to make significant breakthroughs.

While Syriza has its origin in the ‘traditional’ radical left, Podemos is a completely new social or radical-left populist party. The goal of this paper is to examine in which way these electorates are similar despite their parties’ dissimilarities, how they resemble the radical left electorate, and the degree to which they look like the populist electorate described in the literature.
