To: Interested Parties From: David Binder Research Date: January 22, 2019 RE: Preckwinkle’s Support Declines by Near Double Digits Key Findings Two recent surveys conducted by David Binder Research (DBR) show that support for Chicago Mayoral Candidate Toni Preckwinkle 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. Susana Mendoza and Bill Daley continue to run in second and third, with minimal change in their vote share since December. If the election for Mayor of Chicago were held today, for whom would you vote? December 16 January 21 Toni Preckwinkle 24 15 Susana Mendoza 11 9 Bill Daley 10 9 Willie Wilson 6 6 Amara Enyia 6 5 Lori Lightfoot 5 5 Gery Chico 1 4 Paul Vallas 7 4 Garry McCarthy 6 4 Other Candidate 5 5 Undecided/Abstain 19 34 These results strongly suggest an electorate that has soured on Toni Preckwinkle over the course of the last month. Methodology David Binder Research conducted two separate telephone surveys of 500 registered Chicago voters who are likely to vote in the February 2019 Consolidate Primary Election. The first survey was conducted December 12-16, 2018, and the second survey was conducted January 19-21. The margin of error for each survey is ±4.4%. .
