“Polarization and Democracy is a brilliant, qualitative leap forward in our understanding of the relationship between the two in our turbulent times. With a clear eye, it anchors the root cause of present day polarization in an all too rarely acknowledged driver of Latin American politics: The push and pull of politics in highly unequal societies with hegemonic classes highly resistant to reform. Efforts to deepen democracy generate strong defensive reactions. The book then masterfully unpacks the dimensions of contemporary polarization and the mechanisms that drive it. In a triumph of historically grounded scholarship, it makes complex processes intelligible, setting the highest standard for the rest of us.”
