MADISON, Wis. (AP) – Assembly Republican leaders say a $500 million boost in state revenue should be tapped to pay for an increase in public school spending.  The Republicans issued a press release on Thursday saying they would support a $100 per-student spending increase. Senate Republican leaders have called for as much as a $200 per-student increase.  The nonpartisan Legislative Fiscal Bureau released a memo Thursday showing the new, more positive budget estimates. They roughly $500 million increase above earlier estimates will give lawmakers room to pay for additional spending and tax cuts.  Gov. Scott Walker has said in recent weeks that he also wants to increase funding for K-12 schools and broaden his tax cuts as originally proposed.
