This was a pretty good column by former state Comptroller and Attorney General Roland Burris from the Chicago Defender. BTW in 1995 Burris, himself ran against Daley for Mayor as a third party candidate. Needless to say of course that Daley would win that contest.
Anyway that column proved to be a good chronology and analysis of the events that let to the election of Chicago's first black mayor. It's certainly worth a read if you want to read an account from someone who was there to recount these moments firsthand.
ADDITION: Here's another column about Harold Washington this time from US Congressman Danny Davis from the Defender.
