Restrictive voting laws are an increasingly salient feature of American politics. Yet estimating their direct impact on turnout is challenging, given the strategic actions political actors take to impose and mitigate the costs of these laws. Using individual-level data from Davidson County, Tennessee, we leverage variation induced by an early-morning tornado on Super Tuesday 2020 to estimate the direct causal effect of polling-site consolidations. We find moving to a new polling station decreases in-person turnout by 5.65 percentage points, on average, and that the variable cost—proxied by change in travel distance—drives almost all of this decline. Voting at a consolidated site only decreases turnout when the number of individuals assigned to a station increases by more than 100%.
