Five current and past graduate students (Carlos Algara, Sharif Amlani, Sam Collitt, Isaac Hale, and Sara Kazemian) have published an article in Political Behavior on "Nail in the Coffin or Lifeline? Evaluating the Electoral Impact of COVID-19 on President Trump in the 2020 Election."
Among other things, they find "evidence that President Trump gained support in counties with higher COVID-19 deaths." Nicely done!
