Richard Michael Daley (born April 24, 1942) is a United States politician, member of the national and local Democratic Party, and former Mayor of Chicago, Illinois. He was elected mayor in 1989 and reelected in 1991, 1995, 1999, 2003, and 2007. He was the longest serving Chicago mayor, surpassing the tenure of his father, Richard J. Daley, on December 26, 2010. Daley announced on September 7, 2010, that he would not run for re-election in 2011. His term ended May 16, 2011. On May 24, 2011 the University of Chicago announced Daley's appointment as a senior fellow at the Harris School of Public Policy.
Daley was chosen by Time magazine in its April 25, 2005 issue as the best out of five mayors of large cities in the United States, and characterized as having "imperial" style and power, he has presided over a resurgence in tourism, the modernization of the Chicago Transit Authority, the mayoral takeover of the Chicago Public Schools, the construction of Millennium Park, increased environmental efforts and the rapid development of the city's North Side, as well as the near South and West sides. He took over 70% of the mayoral vote in 1999, 2003, and 2007. According to a Chicago Tribune poll taken in late 2009, however, Daley's approval rating was at an all-time low of 35%.
Prior to serving as mayor, Daley served in the Illinois Senate and then as the Cook County State's Attorney.
