Chicago Mayor Richard M. Daley talks with 2016 committee members and supporters at a press conference Friday, Sept. 25, 2009 in Chicago, before he heads to Copenhagen, Denmark, for the 2016 Summer Olympic host city announcement. If Chicago beats out Tokyo, Madrid and Rio de Janeiro in next Friday's vote by the IOC, Daley will cement his place among the world's most powerful mayors _ and, like his father, among his own city's greatest leaders.
