MADISON, Wis. (AP) – Democrats say Gov. Scott Walker’s budget proposal hurts the middle class and public schools and leaves a lot of unanswered questions.   Walker’s two-year spending plan released Wednesday night includes a $343 million income tax cut, a freeze on public school spending and an expansion of private vouchers.  Democratic Rep. Cory Mason of Racine says the budget fails to address the needs of the middle class.  Walker’s income tax cut targets individuals who earn up to $161,180 in taxable income. Democratic Senate Minority Leader Chris Larson says people who make that much aren’t the taxpayers who need the most help.  Democrats also say Walker’s budget making it harder to qualify for Medicaid will decrease the availability of affordable health care.
