Superstorm Sandy and voter vulnerability in the 2012 US Presidential Election: a case study of New Jersey and Connecticut

Superstorm Sandy was an unprecedented meteorological event that devastated the Caribbean and the Northeastern Coast of the USA in October 2012. While many research efforts will focus on the atmospheric conditions that led to the creation and unusual track of the storm, this study evaluates the impact of Sandy on voter turnout in the 2012 US Presidential Election. The goals of this paper are to (1) determine if any alterations in voter turnout occurred, (2) assess the extent to which Sandy was responsible for any voter turnout changes and (3) investigate if the influence of Sandy on voter turnout was contingent upon social vulnerability. To accomplish these goals, voter turnout change between the 2008 and 2012 US Presidential Elections was analysed at the county and municipal level for both New Jersey and Connecticut. The notable decreases in voter turnout discovered in both states were likely due to the election occurring in the aftermath of Superstorm Sandy. The correlation, spatial clustering analysis, analysis of variance and multiple regression results all suggest that storm surge was more likely to be responsible for reduced voter turnout in New Jersey than in Connecticut. Specifically in New Jersey, the findings indicate that storm surge coverage, rather than height, was influential in reducing voter turnout and that this relationship was contingent upon the racial composition of the municipalities. Overall, understanding how Sandy affected voter turnout will help improve the resiliency of electoral systems to future natural disasters.
