The situation I described can be characterized as an "illiberal democracy" or a "hybrid regime." These terms are used to describe countries that possess certain democratic institutions, such as elections, but exhibit authoritarian tendencies or restrictions on civil liberties in practice.
In an illiberal democracy, the democratic processes may exist on the surface, but the government systematically undermines democratic principles and institutions, such as the rule of law, separation of powers, and protection of individual rights. This erosion of democratic norms often leads to the concentration of power in the hands of a single leader or ruling party, and the suppression of dissenting voices.
The term "hybrid regime" is another way to describe a country that combines elements of both democracy and authoritarianism. It acknowledges the presence of democratic features, but also recognizes the dominance of authoritarian practices and policies that undermine the true spirit of democracy.
In the specific case I mentioned, where a country consistently elects authoritarian leaders due to populism or hatred towards a minority group, one might also use the term "electoral authoritarianism." This term emphasizes the manipulation of democratic processes, such as elections, to maintain an authoritarian regime in power, often through the exploitation of populist sentiments or discriminatory ideologies.
Please note that the terminology used to describe political systems and situations can vary, and different scholars or analysts may use slightly different terms or classifications. Nonetheless, the terms "illiberal democracy," "hybrid regime," and "electoral authoritarianism" are commonly used to describe situations where democratic façades coexist with authoritarian practices.
