Is There a 'Party' in Your Genes?

Abstract:     
Utilizing quantitative genetic models, we examine the sources of party identification and the intensity of that identification. The results indicate genes exert little, if any, influence on party identification, directly or indirectly through covariates. However, we find that genes appear to play a pivotal role in shaping the strength of an individual's party identification. Together with recent examinations of political attitudes and vote choice, these findings begin to provide a more complete picture of the source of partisanship and the complex nature of the political phenotype.

Keywords: Genes, Party, ID, Intensity
