This essay focuses on the institutional changes caused by the so-called sovereignisms, that invoke a return to State sovereignty as a point of gravity to redesign global power in national and international relations and promote a “trueµ democracy following a leader. Their institutional style closely resembles that of the Dadaist artistic movement, with its irreverent and derisory attitude towards established rules and settled belief. What they realize are authoritarian forms of democracy and a deep crisis of their institutional frame that parallels the crisis of the representative model. Trump can be seen as an exemplary model of this style and institutional damages caused by his institutional behavior are even more significant since they concern a country with ancient democratic roots and which is the most powerful nation in the world.
