The renewed interest on political realism can offer a new reading of the traditional dichotomy between normative and realist conception of constitutionalism. The purpose of this article is to analyse this renewed discussion, especially by focusing on the relationship between “political realism” and “political constitutionalism,” in the light of some theorists and authors—such as Richard Bellamy and Jeremy Waldron. After a brief introduction in which political realism will be discussed, especially through Bernard Williams’ reinterpretation, the article proposes a rereading of (...) democratic constitutionalism from the classical dichotomy between normativism and realism in political theory. The focus will be set on three key issues: 1. Richard Bellamy’s constitutional theory in a realist perspective; 2. An insight of legal constitutionalism under a normative banner; 3. A brief conclusion in which the risks of a majoritarian and populist constitutionalism will be discussed. (shrink)
