Stephan:   Supreme Court Justice Louis Brandeis, considered one of the greatest legal minds in American history, in his decision on New State Ice Co. v. Liebmann in 1932 described how a "state may, if its citizens choose, serve as a laboratory; and try novel social and economic experiments without risk to the rest of the country." It was and is a brilliant observation, and nowwhere is it being played out more clearly than in Wisconsin and Minnesota. These two states for most of their histories have been social progressive mirrors of one another. But then Wisconsin voters decided to try something different and they elected Scott Walker governor not once but twice. Walker has been in office long enough, and with control of the legislature, powerful enough to have put his stamp on Wisconsin. And what has happened? He has destroyed the union movement, much of which began in Wisconsin and, as this report describes, has devastated the middle class with his policies. During his tenure "incomes [which] were well above the national average in 2000... are now below the national average, according to the data." As his political soulmate Sarah Palin might say, "How's that workin' out fer ya Wisconsin?"
