Protesters who spent the night in Wisconsin?s Capitol vowed Monday to remain as long as necessary to speak out against Gov. Scott Walker?s plan to end most collective bargaining rights and demonstrate against his budget. Walker planned to deliver his two-year budget plan in the state Assembly chamber on Tuesday afternoon. He has said that plan will help make clear why the collective bargaining concessions he is seeking from public employees are necessary to help plug a $3.6 billion shortfall.Walker has said his budget will include about a $1 billion cut in state aids to schools and local governments. He is also expected to propose dramatic changes to how the University of Wisconsin is organized, make cuts to Medicaid and possibly increase fees to help raise money.
