The public employee unions and other liberals are confident that Wisconsin voters will turn out Governor Scott Walker in a recall election later this year, but not so fast. That may turn out to be as wrong as some of their other predictions as Badger State taxpayers start to see tangible benefits from Mr. Walker's reforms—such as the first decline in statewide property taxes in a dozen years.

On Monday Mr. Walker's office released new data that show the property tax bill for the median home fell by 0.4% in 2011, as reported by Wisconsin's municipalities. Property taxes, which are the state's largest revenue source and mainly fund K-12 schools, have risen every year since 1998—by 43% overall. The state budget office estimates that the typical homeowner's bill would be some $700 higher without Mr. Walker's collective-bargaining overhaul and budget cuts.
