Milwaukee Mayor to Challenge Gov. Scott Walker

Democrats in Wisconsin chose Milwaukee Mayor Tom Barrett for the upcoming recall election against Governor Scott Walker, which is set for June 5. It’s been well over a year since Gov. Walker first earned the wrath of Wisconsin Democrats after backing a bill removing collective bargaining rights from public sector union members.  In a proud union state like Wisconsin, the position was met with quick and enduring fury from Democrats and demands for a recall election. Shawn Johnson, capitol reporter for Wisconsin Public Radio, explains what’s happened since.
