question: Objectives: We aimed to analyze the enduring effects exerted by COVID-19 exposure and subjective economic threats on support for anti-democratic political systems. Method: We performed a two-wave longitudinal study on a quota panel of the Italian adult population (N = 1,073), surveyed first in April 2020, during the first peak of the pandemic (T 1) and the first lockdown, and second in October 2020, at the onset of the second peak of the pandemic and of the second lockdown (T 2). Results: A mediation model showed that COVID-19 exposure and subjective economic threats, measured at T 1, fostered a negative evaluation of how the government managed the pandemic, which, in turn, had a positive association with support for anti-democratic political systems, both measured at T 2. Conclusion: The existential threats related to the COVID-19 pandemic have enduring political consequences, undermining people's support for democracy, even six months after their onset.
