How Ideological Diversity Moderates Republican Support for Voter Suppression Measures: The Cases of Georgia and Alabama

Abstract

Abstract Why do Republicans sometimes decline to enact voter suppression measures, even when contextual conditions (unified control of state government, electoral threats from Democrats, and racial threats from African American and Latinx voters) suggest that they should? We argue that ideological diversity within state Republican parties plays an important role in moderating Republican efforts to adopt policies that substantially increase the cost of voting. When a state Republican Party is more ideologically diverse, members may differ significantly on the preferred severity of voting restrictions and the priority of ballot restrictions relative to other issues. Thus, more heterogeneous Republican Parties may be less willing and able to institute voter suppression measures. In contrast, more ideologically unified Republican Parties face fewer barriers to collective action in advancing ballot restrictions, facilitating their adoption of voter suppression measures. We illustrate our arguments with case studies from Georgia and Alabama.
