MADISON, Wis. (AP) – Public school advocates are hopeful they may get more money from the state after Gov. Scott Walker floated the possibility of diverting funding he originally proposed for the University of Wisconsin System.  Walker said Thursday he may take some of the $181 million he originally earmarked for UW and instead use it for school aids. The switch comes in light of UW having $650 million in reserves.  Republican Sen. Luther Olsen is chairman of the Senate Education Committee and a member of the Legislature’s budget committee. He says UW should tap its reserves and the money Walker proposed for them should instead go to schools.  Wisconsin Association of School Boards lobbyist Dan Rossmiller says the money should pay for raising revenue limits to allow schools to spend more.
