"In the public sector, the politicians who approve any deal have none of their own money at stake. On the contrary, the more favorably they dispose of union demands, the more likely they are to be the beneficiary of union largess in the next election. It's the perfect cozy setup...

The Democrats' strength lies in government workers, who now constitute a majority of union members and provide massive support to the party. For them, Wisconsin represents a dangerous contagion."
