For example, some critics of police violence have come around to the view that one of the problems here is the power of police unions, which resist efforts to increase accountability and oversight of their members. There is a political party in this country that is very much committed to increasing the power of public-sector unions, that has worked hard with some success to do that, and that is enormously dependent upon the financial and political support of those unions for its campaign efforts — and it is not called the Republican Party. It’s the other one.

It surely is the case that the African-American children who attend public schools in Philadelphia or Atlanta are subjected to the same racism experienced by other black Americans. But it wasn’t the agents of white supremacy that corrupted their school administrations and made their educational institutions into the dysfunctional failures they are today. It wasn’t David Duke who turned the Atlanta public schools into a criminal conspiracy that ended in racketeering convictions. Progressives have been running the show in big-city school districts for decades, and the mess they are is the mess progressives made of them.

The Democrats are going to have their convention in Milwaukee this year. If Republicans had any wit to them at all, this would present a priceless political opportunity, because Milwaukee is a mess, its schools are an especial mess, and Wisconsin has the biggest black–white academic-achievement gap in the country. Black students in Wisconsin have the second-lowest graduation rate in the country.
