From the Journal Sentinal editorial board that twice endorsed Scott Walker for Governor:
And, of course, there's Act 10. Walker will never budge from his rock-solid support for this law, but he erred by taking such a radical step when a prudent governor would have taken a reasonable step. Act 10 wasn't necessary. It was a particular brand of political overkill designed to make public employee unions less of a factor in state politics. Walker had other options; he didn't have to drop a nuclear bomb on the unions and ignite a polarizing firestorm in the state. Labor costs were a problem, as we've long acknowledged. But other states took less extreme steps and got control of their finances. That Walker chose to do what he did speaks volumes about both his politics and his policy judgment. Act 10 was a mistake.
