Populist presidents often mobilize popular support for their institutional reforms by claiming to promote a democracy that is genuinely responsive to the majority. However, most of the time, they are doing the exact opposite—undermining democracy. Voters, then, should decide whether to support the incumbent’s undemocratic behavior and reforms. In this article, I argue that voters will embrace the gradual subversion of democracy when they approve of the executive’s performance in office, particularly when the populist president is a prominent and influential figure. I test this argument using survey data collected in Mexico under Andrés Manuel López Obrador—an influential populist leader who enjoyed widespread approval and advanced autocratization in the name of democracy. The results indicate, indeed, that López Obrador’s presidential approval not only reinforced the belief that Mexico is a democracy but also increased voters’ support for the president if he decided to disregard the rule of law, curb the opposition’s rights, or cancel the separation of powers. These findings suggest that populist presidents might be able to persuade voters to embrace the subversion of democracy disguised as democratic improvement.
