You guys are focusing hard on the misinformation part, but seem to be skipping by the fact that county voting results and local COVID cases, hospitalizations, and deaths are all easily tabulated public data.
For a host of reasons, it’s very easy to see logic in an assertion that areas that voted more heavily republican correlate with higher rates of COVID deaths and hospitalizations. There’s a heavy partisan political element to vaccination rates, non-pharmaceutical interventions, public health restrictions, etc. One cannot reasonably expect that to not show up in the data when individual health outcomes are linked to vaccination and public policy.
