Brandon Johnson has only been Chicago’s mayor for six months, yet he has already managed to best former Democratic Mayor Lori Lightfoot at chasing away the approval of the electorate.

An Illinois Policy Institute poll conducted from Oct. 18 to 22 by the analytics outfit Echelon Insights found that only 28% of respondents approve of the job Johnson is doing as mayor — the lowest rating for a mayor at this point in the term in the city’s modern history. As a point of reference, the same poll found that Lightfoot had a 28% approval rating ahead of her crushing electoral defeat in February.

While Johnson managed a lower approval rating with the Democratic-leaning cohort than Lightfoot in her final days as mayor, she still outdid him in terms of her disapproval rating with 66% to Johnson’s 50%.

Johnson’s approval rating among voters in the 18-29 age group was 32%. Among voters in the 40-49 age bracket, it was 24%.
