MADISON, Wis. (AP) – The state Assembly has passed the state budget on a 55-42 vote.  The vote came abruptly on Wednesday after Democrats surprisingly decided against offering any amendments. Democratic Minority Leader Peter Barca says Republicans were clear no changes would be made, so Democrats instead were going to take their opposition directly to the public.   The $70 billion budget would cut income taxes by $650 million, expand private school vouchers statewide and reject a federally funded expansion of Medicaid.   Barca says the budget will hurt the middle class and does not reflect the values of most Wisconsin residents.   Republicans defended it as good for the economy and the state.   The budget now heads to the Senate for debate Thursday.
