Wisconsin was running one of the nation's worst state deficits when Walker was inaugurated. The tax cuts and collective bargaining reforms he pushed through the legislature have revitalized the dismal Wisconsin economy and turned a $3.6 billion deficit into a 900+ million dollar surplus and has helped Wisconsin cities save many millions more. Walker's goal of 10,000 new businesses in Wisconsin by 2015 was realized with 13,000 new businesses starting up or moving into the state by the end of 2013 and Wisconsin's real and official unemployment rate is under the national average in a very long time..
School districts now have the ability to hire and fire based on merit and pay for performance and school choice was expanded. Improvements are beginning to show on test scores though it will be some more years before the full effect of that will be known. And that was accomplished with a decrease in statewide school property taxes.
$1.2 billion was added to the Medicaid programs that had been seriously underfunded.
Assuming he would enjoy the same success at the federal level, we could do a whole lot worse than a Scott Walker as President.
