Abstract

This paper studies trends in the partisanship of Congressional speech from 1873 to 2009. It defines partisanship to be the ease with which an observer could infer a congressperson’s party from a fixed amount of speech, and estimates it using a structural choice model and methods from machine learning. This paper applies tools from structural estimation and machine learning to study the partisanship of language in the US Congress. [Working Paper 22423]
