Following the leaders: Asymmetric party messaging in the U.S. Congress

Abstract

AbstractToday, rank‐and‐file members are increasingly removed from the legislative process and often rely on congressional leaders for information to discuss major legislative decisions with constituents. As a result, preparing constituent communication materials has become an institutionalized responsibility for party and committee leaders, leading to a partisan discussion of legislation. Using a mixed‐methods approach of computational text analysis and elite interviews, I demonstrate how members of Congress use leader‐led, partisan messages for constituent communication. Echoing prior work on asymmetric partisanship, I find that Republican leaders are more likely to encourage party‐centric messaging, and rank‐and‐file Republicans, particularly in the House, are more likely to adopt party messaging. The findings illustrate the institutional power of party leaders in a centralized Congress, as well as the role that constituent communication plays in encouraging and maintaining asymmetric polarization.
