CHICAGO (WLS) --
New poll numbers out from the Chicago Tribune suggest a mayoral race featuring incumbent Rahm Emanuel and teachers union president Karen Lewis would be a close one. It gives Lewis a slim 4 percent lead.
It also suggests that Mayor Emanuel's approval rating is falling sharply, currently at 35 percent which is down from 50 percent a little more than a year ago, with more than half of city voters disapproving of how the mayor handled his first term.
A 4 point lead for an unannounced candidate against an incumbent mayor with high name recognition and national media fluffing might be slim, but it's also a big deal.
