MILWAUKEE, Wis. (WTAQ) - Milwaukee County Executive Scott Walker says small is better when it comes to schools. Walker is running for Wisconsin governor as a Republican. He says the state's biggest school district should be broken down into 10 or more autonomous districts, saying the split would make it easier to provide an education for Milwaukee public school students. A campaign spokesman for Democratic candidate Tom Barrett calls Walker's idea "half-baked." Barrett has backed a measure that would give the mayor's office control of Milwaukee Public Schools.
