The federation—along with several locals of the Service Employees International Union that are CFL members—has vowed for months to get rid of aldermen who, in its view, aren’t looking out for the city’s workers. Opponents of the big-box minimum wage ordinance were named as top targets; even before Mayor Daley vetoed the measure in September, some union leaders announced that they were going to provide labor-friendly challengers with campaign armies and cash.

The CFL does pledge support to ten challengers, among them Pat Dowell, who’s trying to unseat 3rd Ward alderman Dorothy Tillman; Sandi Jackson, wife of Congressman Jesse Jackson Jr., who hopes to take out 7th Ward alderman and recent appointee Darcel Beavers, the daughter of longtime alderman William Beavers; and Carina Sanchez, who’s vying for the 12th Ward seat now held by George Cardenas, who at the mayor’s behest flipped from supporting to opposing the minimum wage ordinance.
