Minneapolis residents are defending city walls as best they can against masked federal Immigration and Customs Enforcement agents who shot and killed two 37-year-old nonviolent resisters. Minnesota represents the best of the Upper Midwest blue states, along with Wisconsin, Illinois and Michigan (Iowa excluded). In a cruel and bleak midwinter, Minneapolis residents are not staying home in the cold crush of ice and snow. Trump’s campaign in Minnesota is partly based on racial grievance, as the state took in a large population of Somali migrants. The rest of us owe Minneapolis a debt of gratitude for fighting our battles for us.
