Say what you will about Whitmer's COVID-19 measures, but at least they weren't racist. Evers' were, and he marketed them as such. He's a terrible messenger and will probably lose by more than Whitmer.
How were they racist?
Free testing only for minorities.Ethnic minorities were disproportionately affected by the virus, so it wouldn't have been surprising to see the response focused on their communities. However, ethnicity was hardly the only variable in determining vulnerability to the spread of/death by the coronavirus, and the measure excluded white people in majority-minority neighbourhoods. Tests should have been offered for people of any race in a badly affected area, and if they had to be prioritised for individuals, they should have been prioritised for older people and people with preexisting medical conditions.
Frankly, free testing should have been rolled out across the state (this happened later). I suspect testing was prioritised here because Evers wanted to virtue signal rather than because of capacity issues.
