Gov. Scott Walker (R-Wisc.) wasn’t a household name across the U.S. when he won the midterm election, but he is now. Walker’s move to rein in employee costs for his state and the response by labor unions to mobilize the troops have made the governor a household name. Walker is facing a billion-dollar-plus money shortage, and his efforts to get teachers to pick up more of their pension and health insurance costs have spurred union outrage. Fact is, 45 states will run short in 2012, and most governors are looking for ways to balance the spending with the revenue.
