The proposition that voter roll-off is context-specific is tested in t
he context of the racial composition of the electorate and of the fiel
d of candidates competing for office. Examination of voter roll-off in
28 New Orleans city council elections held from 1965 through 1986 ind
icates that roll-off among black voters was responsive to the number o
f black candidates competing for office. The authors conclude that thi
s is because black candidates generate a greater level of political in
terest among potential black voters in local elections. Roll-off among
white voters was unrelated to the electoral context. The authors spec
ulate that this may be due in part to racial differences in feelings o
f political efficacy.
