The political theater continues in Wisconsin as news broke over the weekend that a federal judge struck down key parts of Governor Scott Walker’s union-busting bill.

According to the ruling, the state can’t prevent public employees from collecting voluntary dues through payroll deductions and it can’t require they recertify annually.

Public safety unions were largely exempted from the provision, which led the court to rule on Friday that Wisconsin did not have the right to choose which public unions could be exempted under the current collective bargaining law.

On the heels of the court’s ruling, Milwaukee Mayor Tom Barrett announced his plans to run against Walker in the June recall.

Barrett says it is time to bring “Wisconsin back.”

Barrett ran against Walker for the governorship in 2010 receiving 47 percent of the vote.  In a poll released last week, Walker holds a slight edge over Barrett with 47 percent to 45 percent

Barrett also ran for governor in 2002.

Three other candidates have announced their intentions to compete for the Democratic nomination for governor in the upcoming recall, including: Secretary of State Doug La Follette, State Senator Kathleen Vinehout and former Dane County Executive Kathleen Falk.
