red state – blue state – vaccinated state – unvaccinated state

The New York Times published an article demonstrating the partisan separation between US Democrats and Republicans by regression lines. As the one above, regressing the proportion of vaccinated on the proportion of Trump voters but no scale on the first axis. But no correction for age composition or population density. And the one below, plotted at the county level, which seems quite meaningless given the spread of red dots in Wyoming.

Still, there is a clear opposition between places (counties) that voted more than 70% Trump (representing 33M people) and those that voted more than 70% Biden (more than 58M people), even though county density, age composition, and earlier deaths from COVID should also be accounted for. But the vaccination rate also exhibits this opposition, with a 1.65 ratio between the first and last decile of the blue counties.

  1. Unless this data is adjusted for age (and other confounders) this comparison is probably quite meaningless. Probability of death by COVID and probability of voting republican are both strongly correlated with age.
