Independent Political Networks: Comparing the Discussion Network Size and Composition of Partisans, Leaners, and Independents

Abstract Most prior U.S. political discussion research has failed to pay close attention to the networks of political independents, and to the differences between true partisans, leaners, and true independents. This is in direct contrast to the (appropriately) growing research attention paid to the decades-long rise in the proportion of independents and the decline of true partisans. This study presents representative U.S. survey data that compares political discussion frequency, network size, and the partisan composition of the discussion networks of partisans, leaners, and independents. After applying controls for ideological strength and political interest, we find that the three groups do not differ in discussion frequency or network size. However, there are meaningful differences across the groups in three different network composition measures, including partisan bias. We interpret our findings in the context of both applied measurement considerations and normative democratic expectations of partisan diversity within discussion networks.
