How do populist publics visually represent themselves, and how have shifts in visual technologies altered this process? While research on the visual politics of populism has largely focused on ‘top-down’ uses of imagery by populist leaders and parties, less attention has been paid to how ‘the people’ depict themselves from the ‘bottom up’. This article addresses this gap by theorising the concept of the visual self-mediation of ‘the people’ and tracing its evolution across two emblematic episodes in which contested claims to popular sovereignty were visually enacted: the 2002 Venezuelan coup attempt against Hugo Chávez and the 2021 US Capitol riots. Through a structured, diachronic comparison, the article identifies a broader historical shift – from televisual mediation of ‘the people’, dependent on elite controlled platforms, to digitally enabled self-mediation, wherein publics broadcast themselves as ‘the people’ in real time via smartphones and social media. It analyses how populist publics visually presented themselves, as well as the intended and unintended audiences for these visuals. In foregrounding this transformation, the article contributes to ongoing debates in visual politics, media ecologies, and populism by illustrating how digital infrastructures have reconfigured the visibility, performativity, and legitimacy of populist publics in the twenty-first century.
