Poll: Mayoral race between Emanuel, Lewis would be close

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.
