With few exceptions, voter turnout continues to decline in the United State
s. Although normative theorists, journalists, and defenders of participator
y democracy frequently suggest that citizen-initiated ballot measures can i
ncrease voter turnout, previous research has not supported this claim. Yet,
in the past 25 years, usage of direct democracy has exploded in the United
States. Using pooled time series data for the 50 states over a 26-year per
iod (1970-1996), we find that the presence and usage of the initiative proc
ess is associated with higher voter turnout in both presidential and midter
m elections. The disparity in turnout rates between initiative and noniniti
ative states has been increasing over time, estimated at 7% to 9% higher in
midterm and 3% to 4.5% higher in presidential elections in the 1990s. Our
analysis suggests that the initiative process can and does play a positive
role in increasing electoral participation.
