Daley departure tells us a lot about the media

The Chicago Tribune’s banner headline on Tuesday, September 7, the day Mayor Richard M. Daley announced he would not seek a record seventh term, read: “City wants $1 billion more for O’Hare Plan.”

This signaled two things, one obvious, the other less so . . . but worth exploring, for it helps explain why Daley is calling it quits after 21 years in office.
