Does federal pandemic aid boost incumbent performance in state elections?
Core argument: Each additional senator or representative per million residents predicts roughly $1,000 more COVID-19 aid per capita, and overrepresented states received systematically more federal pandemic funding.
Identifying the effect of revenue windfalls on economic voting is challenging because whatever conditions led to the influx of cash might also benefit or harm incumbent politicians for a variety of other reasons. We leverage the fact that pandemic assistance varied based on congressional representation, with an additional senator or representative per million residents predicting roughly $1,000 dollars in additional aid per capita. As a result, overrepresented states received systematically more funding. By predicting aid levels using congressional representation as an instrument, we seek to isolate the effect of COVID-19 spending on state-wide election results. We find that federal pandemic aid strongly predicts incumbent performance in the 2020, 2021, and 2022 elections. The exclusion restriction here [the basis for the econometric identification] assumes that higher per capita representation in Congress did not benefit incumbents through channels other than the increase in COVID-19 funding.
