After thousands of voters revolted over Wisconsin Gov. Scott Walker’s stripping public workers of their collective-bargaining rights last year, they’re taking the next step to get him out. Organizers of a sprawling campaign to recall Walker will deliver more than 1 million signatures to a state board, nearly twice as many as necessary, marking the beginning of an extended process that could lead to a recall election. The Democratic Party said it will deliver the 3,300 pounds of signatures Tuesday, and Wisconsin’s Government Accountability Board will have 31 days to sign off on them.
