From the OP:
"More than three-quarters of Twin Cities residents over the age of five have been vaccinated, according to data from Minneapolis and Ramsey County."
This is a measure of their resolve: At least 76% of all Minnesotans 5 years-old or older are vaxed, and they still declare a mandate.
In other words, the target is 100%, and they're going to pull out all stops to get there.
