The debate over public workers' unions took over the old state Capitol building in downtown Raleigh Saturday afternoon. A few hundred people joined a rally organized by the State Employees Association of North Carolina and MoveOn.org to support state employees in Wisconsin who would lose collective bargaining rights under a budget-cutting plan. They carried signs with slogans like "Unions make us strong" and "Fund pensions, not wars." Between 100 and 150 people belonging to various conservative groups held a counter-protest across the street. They held signs declaring "SEIU/SEANC, your gravy train is out of steam," "Rein in public sector unions"...
