The making of electoral rolls is a crucial political and democratic question: it depends on incisive and competing conceptions of the demos, and these electoral rolls are always susceptible of being politicized. This happened in post-WW2 Italy. When democratic institutions were stabilizing, political competition between the DC and PCI was intensifying, especially at the local level, and internal and international migrations rose again. This politization ended with a coincidence rule between local residency and exercise of one’s voting rights that still prevails today.
