Get Out the Vote-by-Mail? A Randomized Field Experiment Testing the Effect of Mobilization in Traditional and Vote-by-Mail Precincts

This study extends previous field experimental research on turnout by considering how institutional context moderates the effect of mobilization. Taking advantage of a setting in which some registrants are assigned to vote by mail, the authors find that a door-to-door mobilization campaign has a larger effect on the participation of those who vote at polling places than on registrants assigned to cast mail ballots, but only among individuals whose voting behavior is most likely to be shaped by extrinsic social rewards. The authors conclude that there may be payoff for election reform strategies that tap into voting’s social rewards.
