While hardly surprising to anyone who read the polls, yesterday’s victory by Republican Governor Scott Walker was a body blow to Wisconsin unions and to American workers. Within Wisconsin, Walker’s victory ensures that his law repealing collective-bargaining rights for public employees will stay on the books, and if Republicans maintain their hold on the state senate—four of their senators faced recall elections, and as I write this at least three have survived—they will, at least in theory, be able to go forward on other parts of their Social Darwinist agenda. Whether they will—and whether they opt to go after private-sector unions, too, with right-to-work legislation—remains unclear. Such a move on Walker’s part, coming on the heels of the most divisive 18 months in the state’s history, would only escalate what is already a political civil war. Even Walker may think it the better part of valor to pass on that for now.
