Last night on Vliet Street, Milwaukee Public Schools superintendent Gregory Thornton and the Board of School Directors sketched out what Thornton called a "worst case scenario" for next year's school budget. On top of the already-projected loss of $13 million in state funding -- and tens of millions of dollars in federal funds -- for fiscal year 2012 the governor's proposed budget would, according to the scenario presented on Thursday, slash another $74 million from Milwaukee's public school system.
