An Experimental Test of Mobilization Effects in a Latino Community

This article describes a field experiment designed to test the efficacy of get-out-the-vote (GOTV) techniques in a new context and for an understudied population. It evaluates the effectiveness of nonpartisan GOTV messages delivered via personal contact and mail in a heavily Latino community during the 2004 presidential campaign. It proposes and tests an alternative model of voter turnout based on Zaller's receive—accept—sample model of public opinion. The findings are consistent with the authors' predictions; mobilization efforts increase turnout, but mobilization effects vary across citizens based on their propensity to vote. There is a large increase among episodic voters but little increase among habitual or registered nonvoters.
