FILE - In this Aug. 28, 1968 file photo, Mayor Richard J. Daley pumps his fist as he speaks from the floor of the Democratic National Convention in Chicago. In the years since 1968, a second Mayor Daley has come and gone. Former Mayor Richard M. Daley, who took over the city 10 years after his father died and then retired last year after 22 years in office, is largely credited for helping to lead the city’s transformation from a gritty industrial center to a booming hub of international commerce. The city will have the international spotlight when it hosts the NATO summit May 20-21, 2012 and give the city and Mayor Rahm Emanuel a chance to hone its image. (AP Photo/File)
