"What's happening in Wisconsin is not complicated. At the beginning of this year, the state was on course to end 2011 with a budget surplus of $120 million. As Ezra Klein explained, newly elected GOP Governor Scott Walker then ' signed two business tax breaks and a conservative health-care policy experiment that lowers overall tax revenues (among other things).
The new legislation was not offset, and it turned a surplus into a deficit.' (Update: please see this note for more detail on the cause of the budget gap.)"
