On April 4, 1967, Mayor Richard J. Daley won reelection to his fourth consecutive term in office. Daley beat his opponent, Republican John Warner, by a vote of 792,238 to 272,542.
Only two mayors in Chicago history have matched this feat. The first was Carter Henry Harrison, who won reelection to a fourth term in 1885. The second was Daley’s son, Richard M. Daley, who won his fourth term in 1999 and was reelected twice more, in 2003 and 2007.
