Radicalization, polarization and post-truth. Challenges and uncertainties for the rule of law

This article aims to show the consequences of the use of political marketing 3.0 by political parties and leaders in the Rule of Law. All of this is the result of various investigations that analyze different phases of political marketing 3.0. In this case, we would be talking about the fourth phase of the project, which sought to demonstrate that 21st century politics represents a significant challenge to the current Rule of Law, thus compromising objective 16 of the 2030 Agenda, which advocates "Peace, justice and strong institutions." Polarization, populism and post- truth fuel doubts about public institutions, benefiting the "extremes" in the midst of chaos. In addition, it is observed how these political marketing strategies intensify citizen distrust and erode the legitimacy of democratic institutions, creating an environment conducive to manipulation and social control.
