Richard M. Daley was Chicago's mayor for a then-record breaking five terms. In 1967 Daley entered the race for his fourth term against Republican nominee John L. Waner. In the past Daley had failed to receive support from the white electorate, though he was reelected due to overwhelming support among black Chicagoians. In 1967 Daley adopted a much more conservative stance on race, attempting to win back the white voters by planning a housing redesign that cleared slums and "protected" white citizens against the "encroachment" of black families. Daley won the election in a landslide, taking all 50 city wards and receiving more votes than he had in all three previous elections.
