A "big data" analysis of the 2019 Chicago Mayoral race

Chicago mayoral race in the REPL

The 2019 Chicago mayoral race has 14 candidates. Some weeks ago, I read this questionnaire on the WBEZ website, where 13 of the 14 candidates are asked 19 (not 20, as advertised on the article) yes-or-no questions. The article is useful, but it doesn't tabulate the results.

So, I did. I went through the list of questions, and graded each question as to which answer would be progressive. I scored a +1 for a progressive response, a -1 for a non-progressive response, and a 0 for no response. I then tabulated the responses for all of the candidates, then wrote a computer program to connect their responses for each question to the progressive score I devised, tallied the results, and sorted by their total score.

The result is listed above, in the screenshot of a Clojure REPL, and also below in an easier-to-read format.

CandidateScore
Garry McCarthy15
Amara Enyia15
Lori Lightfoot10
Toni Preckwinkle8
John Kozlar7
Susana Mendoza7
LaShawn Ford6
Bob Fioretti5
Gery Chico5
Paul Vallas5
Willie Wilson3
Jerry Joyce-2
Bill Daley-2

There are some things I expected:

  1. Amara Enyia, perhaps the most progressive person on the ballot, scored tied for first.
  2. Bill Daley, the former Commerce secretary and executive committee member of Chase bank, scored tied for last.
  3. Lori Lightfoot and Toni Preckwinkle, perhaps the second and third most progressive people on the ballot, scored second and third, respectively.

There are some things I didn't expect:

  1. Gerry McCarthy, the former Chicago chief-of-police who crushed Occupy Chicago and got fired in the wake of the Laquan McDonald scandal, is tied for first?
  2. See #1.

Some caveats:

  1. There are a great many issues not covered in the questionnaire (Where's the question about TIFs? Hello?!), so the score tabulated here may not necessarily reflect the full policy philosophy of a given candidate.
  2. I only tabulated based on the yes/no/didn't-answer replies given on the questionnaire. Some candidates, to their credit, didn't pin themselves to a binary yes-no, giving answers with a degree of nuance. Such nuanced answers, however, would have gotten discounted in this analysis.
  3. I made a judgment call as to what response to a given question would count as progressive, and one may question my judgment for such a scoring the questions the way I did. To which I say: If you feel you can do a better job, be my guest. The source code and data are publicly available on Github, and you're welcome to fork the repository and change the scores (found in the "resources" directory) and/or the code as you wish.
