One prediction of the calculus of voting is that electoral closeness positively affects turnout via a higher probability of one vote being decisive. I test this theory with data on all mayoral elections in the German state of Bavaria between 1946 and 2009. Importantly, I use constitutionally prescribed two‐round elections to measure electoral closeness and thereby improve on existing work that mostly uses ex post measures that are prone to endogeneity. The results suggest that electoral closeness matters: a one standard deviation increase in closeness increases turnout by 1.27 percentage points, which corresponds to 1/7 of a standard deviation in this variable. I also evaluate how other factors such as electorate size or rain on election day affect turnout differentially depending on the closeness of the race. While rain decreases turnout on average, this effect is mitigated in close elections, as indicated by a positive interaction effect of the two variables.
