Key Findings

Two recent surveys conducted by David Binder Research (DBR) show that support for Mayoral Candidate has declined precipitously since mid-December. DBR conducted a survey of 500 likely voters from December 12-16, which showed 24 percent were inclined to vote for Preckwinkle at that juncture. The most recent survey, which was conducted January 19-21, showed that just 15 percent would vote for her, representing a 9- point drop in support.

The most significant decline in support for Preckwinkle came among white women, among whom 32 percent supported Preckwinkle in December. In the January survey, only 13 percent supported Preckwinkle, representing a 19-point decline in support.

The marked decline in support for Preckwinkle comes as support for other leading candidates has remained relatively constant. and Bill Daley continue to run in second and third, with minimal change in their vote share since December.
