Emanuel, the hard-charging mayor is intent on fixing what ails the nation’s third-largest city, no matter whom he ticks off in the process. The man once nicknamed “Rahmbo” for his fierce political maneuvering, last week announced an agreement with several unions to help bail out the nation’s worst-funded city pension systems, a festering problem inherited from his predecessor, Richard M. Daley. Emanuel said the deal, which would slice Chicago’s nearly $20 billion shortfall in half by cutting benefits and raising property taxes, would keep the funds from insolvency and avoid massive cuts in services and a record tax hike.
