Previous research has examined the impact of the majority vote or runo
ff election requirement on the success of minority and incumbent candi
dates in the South. This study examines the consequences of runoffs in
Chicago city council elections. Contrary to allegations that runoffs
disadvantage minority candidates, from 1975 to 1991 both minorities an
d women were advantaged by the majority vote requirement in Chicago. I
n addition, the runoff appears to have been a crucial factor in the re
placement of Daley-machine black councillors in the late 1970s and 198
0s with allies of Harold Washington.
