Referendums: Yes or No?

Behind referendums and plebiscites lies the idea of popular sovereignty. The key factor in referendums is who has the right to call them. Formally, the Kurdish and Catalan referendums were both illegal because neither the Iraqi nor the Spanish government licensed them. Some places—California and Switzerland among them—have for many years granted a specified minimum of petitioners the right to hold a referendum. But now, globalized social media are transforming the whole ballot initiative question.
