David Blaska:

For our liberal/progressive acquaintances have run out of excuses. After all, they have owned the public school system, through the teachers union and its Democratic Party subsidiary, for the last 30 years or so.
Nowhere more so than in Madison, Wis., where not a single conservative serves on the 20-member Common Council, where the seven members of the current Madison School Board range on the political spectrum from Left-liberal to Hugo Chavez. (Beth Moss, Marjorie Passman, and Arlene Silveira are Progressive Dane.)
History, not conspiracy: The Left has had its hands on the controls of city government since Paul Soglin beat Bill Dyke in 1973 and the Madison School Board since forever.
Madison’s dominant Left is gagging a fur ball because its public schools have failed the very people liberal/progressives claim to champion. The Madison Metro School District graduates fewer than half – 48% – of its black students and only 56% of its Latinos.
Blacks and Latinos, where would they be without the tender ministrations of the liberal welfare state – living evidence of Republican perfidy! Clucked and cooed over in the tenured parlors of well-meaning West Side liberals – people like Nan Brien, Anne Arnesen, Barbara Arnold, and Carol Carstensen. All four ladies presided over this educational debacle as former Madison School Board members. Despite all evidence, these liberals are not one bit abashed by their failure, so strong is their faith in the powers of more spending and more government.
The Urban League’s school must not be approved, the four women write, because “Madison Prep will not be accountable to the Madison School Board nor to the taxpayers of Madison.” Touching, this sudden concern for the taxpayer. (Madison Prep Academy would cost the school district $17-28 million over five years. Supt. Nerad’s plan would cost $105.6 million over five years.)
Some would say that the Madison School Board has not been accountable to its children of color OR its taxpayers.
