In 1979, Indiana University Press published Milton Rakove's book WE DON'T WANT NOBODY NOBODY SENT. Professor Rakove interviewed powerful Alderman Burke. Here's a quote on page 144 from Alderman Burke :
There is a latent anti-Semitism in Chicago and a large population that will never vote for a Jew. They would vote for anybody before a Jew.For Alderman Burke's view on a certain African-American police brutality victim. I guess Cook County Democrat aren't too bothered with the views of certain Democrats.
