​Politicians are increasingly adopting populist rhetoric that is appealing to people's emotions and biases rather than their rational judgments. This rhetoric includes claims of representing the people (us) as opposed to the establishment and the traditional elite (them). Anti-elitist populism manifests in its opposition to facts, with populists becoming the main players who distort facts and spread disinformation. Therefore, populism and disinformation reinforce one other, creating a cycle of manipulation that undermines democracy. By conducting a comparative qualitative analysis of the speeches of Abdel Fattah El-Sisi in Egypt and Kais Saied in Tunisia, this study argues that there are four tactics, rely on disinformation, used by authoritarian populists to legitimize the obstruction of constitutional and institutional constraints and suppress the opposition: (1) constructing the people by creating the enemy; (2) attacking the media and democratic institutions; (3) creating illusion by amplifying achievements; and (4) employing conspiracy theory and misinformation to justify failure at fulfilling promises.
