When I moved to Madison in 2001 to take a job as an assistant professor at the University of Wisconsin, I knew embarrassingly little about my newly adopted state's historical significance. Judging from their wisecracks about the sociology of cows, neither did my friends in New York. I soon learned about Wisconsin's prominent role in many of America's social advances, from “Fighting Bob” LaFollette's opposition to powerful railroad trusts, to pioneering contributions to social insurance, to the nation's first law for public-employee bargaining in 1959, to the turbulent campus protests against the Vietnam War in the 1960s. Little did I know that a decade after my arrival, Wisconsin would once again become “ground zero,” as some commentators now call it, in America's ongoing struggle between democratic progress and reaction.
