Chicago Teachers Union President Karen Lewis is putting her money where her mouth is.
She's donating $40,000 of her own money to her campaign fund.
Lewis says she faces an uphill battle in the money race with mayor Rahm emanuel, but this is another sign that she's seriously considering running against him in next year's mayoral campaign.
According to the Chicago Tribune, Lewis has been holding discussions in neighborhoods across the city as she considers whether to run for mayor.
A Tribune poll published last month showed Lewis leading Chicago Mayor Rahm Emanuel 43 percent to 39 percent, just outside the survey's 3.5 percentage point error margin.
Also considering a bid for mayor is Ald. Robert Fioretti, 2nd.
