Wisconsin Gov. Scott Walker refused Wednesday to back down from his plan to take away nearly all collective bargaining rights from most public workers and force them to pay more for benefits, despite news that the state?s budget is in better shape than previously expected. Walker pushed for the collective bargaining concessions as a way to help address the state?s projected $3.6 billion budget shortfall. But on Wednesday, a new economic forecast said the state will receive $636 million more in tax collections than expected when Walker unveiled his plan _ almost double what would be saved through forcing workers to pay more for health and insurance benefits. No matter the spin, the nonpartisan Legislative Fiscal Bureau?s more positive economic forecast will almost certainly increase the pressure on Walker and the Legislature to rethink some of the most dramatic cuts in the governor?s budget. Those include $1 billion in cuts to schools and local governments, a $250 million cut to the University of Wisconsin System, and changes to the popular SeniorCare prescription drug program.
