What is up with Wisconsin? The state that brought us the labor union and five day work week, the first state to ratify the 19th Amendment, the state once known as the "laboratory of democracy," has also brought us Joseph McCarthy and Scott Walker, and has become one of the most closely divided battleground states in the country. How did we get here, and how does what has happened here in this state reflect larger trends in American politics--a harbinger of what is to come, or how we can fix it?
