This study examines the problem of voter turnout from a rational choice per
spective. It reviews the "paradox of voting" and finds one model, which inc
orporates the role of intermediary social groups and leaders, to be a promi
sing solution. It tests the hypothesis that leader mobilization increases v
oter turnout, using an ecological analysis of turnout in five Montreal ethn
ic communities during three recent elections: the 1993 Canadian federal, th
e 1994 Quebec provincial, and the 1994 Montreal municipal elections. Data o
n mobilization are taken from semi-directed interviews with association lea
ders in each community. The results compare predicted and actual rankings o
f turnout for each community and election. The overall results are weak, in
dicating that the model does a poor job of predicting voter turnout.
