How does the spread of Covid-19 affect voting? Do voters “rally around” incumbent candidates, or is it mostly right-wing candidates who profit from the external threat posed by the coronavirus? We address these questions focusing on the unique case of the French municipal elections that took place in March and June 2020, while Covid-19 cases were spreading across the country. We combine voting data at the municipality level with the excess mortality rate that is plausibly related to Covid-19 in the same municipalities to exploit the geographical variation in the diffusion of the virus. Preliminary results based on diff-in-diff analysis indicate that support for incumbent candidates increased in the areas that were strongly affected by the coronavirus. However, it is mostly right-wing, incumbent candidates – and not other incumbents – who profit from the spread of Covid-19 in terms of increased vote share.
