ABSTRACT Over the last decade, Latinos have exercised rapidly growing influence in elections. This trend has coincided with the closing of the so-called digital divide between Anglos and Latinos and increased use of social media platforms for constituency outreach by members of Congress. Leveraging a battery of indicators associated with Latino outreach by U.S. representatives in communications via Twitter throughout the 112th Congress (the first “tweeting” Congress), we demonstrate that representatives pursue digital home styles oriented toward specific demographic constituencies, and, furthermore, reveal that representative ethnicity shapes Twitter outreach to Latinos in ways that have important implications for the substantive representation of Latinos. Our findings build on previous research which to date has largely presumed that Twitter outreach is characterized by relatively homogenous in-party communication patterns, and has identified only limited evidence that representative ethnicity impacts digital home style.
