Communicating with constituents about Washington activities is a core aspect of a legislator’s job, and one of the most important communication tools that incumbents have is franked mail. The franking privilege has long been recognized as one of the main benefits of incumbency, providing legislators with a free way to contact constituents that challengers do not have access to. In this project, we seek to remedy this oversight by creating a novel dataset of all franked mail from 2018 to 2024 and investigating how legislators discuss their Washington activities. We use this new data to systematically investigate what activities and policy areas members emphasize and how they relate to and discuss political institutions – including Congress and the parties. We then explore whether negativity against their party or the institution affects campaign contribution amounts from various sources.
