AbstractKey [1949. Southern Politics in State and Nation. New York: A.A. Knopf] observed voters tend to support local candidates at higher rates, a phenomenon he termed “friends-and-neighbors” voting. In a recent study, Panagopoulos et al. [2017. Political Behavior 39(4): 865–82] deployed a nonpartisan randomized field experiment to show that voters in the September 2014 primary election for state senate in Massachusetts were mobilized on the basis of shared geography. County ties and, to a lesser extent, hometown ties between voters and candidates have the capacity to drive voters to the polls. We partnered with a national party organization to conduct a similar, partisan experiment in the November 2014 general election for the Pennsylvania state senate. We find localism cues can stimulate voting in elections, including in neighboring communities that lie beyond the towns and counties in which the target candidate resided, at least among voters favorably disposed to a candidate and even when voters reside in the home county of the opponent.
