We divide up the states according to the October 8th, 2020 NPR report https://www.npr.org/2020/10/09/921596963/npr-electoral-map-biden-lead-widens-again-with-less-than-a-month-to-go.
We then use the JHU data at https://github.com/CSSEGISandData/COVID-19 to get the daily confirmed cases for each state, seen below (click on the chart image for the Excel workbook, then click on the Chart1 tab to access the chart):
It is noticeable that the Trump states have more cases (for example note the difference in the Y-scales).
