Conversations about a potential takeover of the Milwaukee Public Schools continue, with politicians considering ideas ranging from letting the mayor run it to creating a pseudo MPS czar. Last week, the Public Policy Forum released a report that looked at other cities with mayoral control over the school system. Mayor Tom Barrett hasn't entirely dismissed the idea, which was entertained by former Mayor John Norquist some time ago. Another pitch would have the mayor appoint a "chancellor," and that chancellor would appoint the school board.
