This is a load of crap.
If legislators sitting on a budget conference committee cannot reconcile conflicting desires and ideologies and put a document before the state Assembly and Senate by mid- to late October, school districts will be at a loss to tell cities how much in tax levies they will need.
As has been explained time and time again, if the state budget is not passed, the state continues to operate under the previous budget. So school districts can ask to levy exactly what they did last year and they will be just fine. They may have to adjust their spending, but their tax revenue is settled.
Perhaps if the Democrats would stop impeding progress with their insistence on a massive tax increase, Wisconsin could have a new budget.
