Perhaps the most significant hurdle for Emanuel will be re-establishing people's trust in him. Too often he's sent the message that he's more about spin, politics and changing the subject than about accepting bad news and, when necessary, responsibility for it. Police accountability, crime rates, city finances, the loss of businesses and jobs in struggling neighborhoods — all of these and more are in flux. The mayor — who, before his re-election, lost connections with minority communities and was widely viewed as a limousine liberal committed only to wealthy donors and downtown development — still has a lot of Chicago commoners to persuade. There might not be enough blue sweaters.
