Hello Amparo & Leo, I do share Amparo’s concern. To have direct democracy more than referenda is needed. May I refer to the working of the Swiss (Con-)Federation (a Federation since 1848), from town governments to the federal government? There is a lot of publications about it. I refer to start the study of its federal constitution (1999) to European Federalist Paper no. 20. A coincidence is that I started to make the analysis of the democratic lock down in Europe, since the French Revolution in 1789-94.
