The emergence of neopopulism in several countries in Latin America has been described by political science literature as the success of a political strategy in which a leader, generally bearing a strong personality and charismatic appeal, seeks popular support in an almost direct form, and overshadows political parties, the external mechanisms of control which define a democratic regime . This article adopts this definition of the concept and argues that the success of this strategy can be analyzed as a relation between supply and demand for populism. The supply refers to the political process which allows leaders to make use of features such as charisma and anti-political and polarizing speech to obtain the support of the public based on their non-programmatic and personal qualities. The demand is defined as the presence of certain preferences within the public, which increase the chance of success of the neopopulist strategy adopted by the leaders. Amidst that relationship, we can place fragile intermediate institutions, mainly the political parties, which would limit themselves to working as vehicles centered on the figure of the leader in order to allow his success among voters. Before going any deeper into the arguments regarding the relationship between supply and demand for neopopulism, the next item will discuss the concept of populism in its more contemporary form.
