Democratic backsliding occurs incrementally, but the empirical study of how citizens respond to undemocratic politicians has been predominantly static. I formulate and test predictions about how different sequences of backsliding shape accountability. Using a novel preregistered experiment (
$N = 4,234$) capturing the reality that democratic transgressions are committed by elected officials step by step, I find that a majority of American respondents – against the backdrop of partisan and policy interests – are willing to electorally remove the incumbent as episodes of democratic backsliding unfold. Moreover, incumbents who incrementally decrease the severity of democratic transgressions are held accountable more promptly than incumbents who incrementally increase or sporadically vary the severity. By establishing a new experimental framework to study democratic backsliding, my dynamic approach not only paints a more nuanced picture of Americans’ willingness to defend democracy, but also demonstrates that sequence matters in shaping voter behavior amid incremental transgressions of democracy.
