Partisan Mobilization Campaigns in the Field: Results from a Statewide Turnout Experiment in Michigan

Political parties have recently rediscovered grassroots tactics for voter mobilization. The only solid evidence for the effectiveness of such get-out-the-vote (GOTV) tactics is based upon non-partisan field experiments that may not accurately capture the effectiveness of partisan campaign outreach. In order to address this lacuna, during the 2002 Michigan gubernatorial election, a large field experiment across 14 state house districts evaluated the cost effectiveness of three mobilization technologies utilized by the Michigan Democratic Party's Youth Coordinated Campaign: door hangers, volunteer phone calls, and face-to-face visits. Contrary to past non-partisan experiments, our results indicate that all three GOTV strategies possess similar cost-effectiveness.
