We are releasing a new version of our state and chamber-level aggregate data. We have focused on two major updates:
- In all, we have 140 chamber-years of new data. These now include party data for Nebraska thanks to friend and coauthor Seth Masket, who generously provided the informal but well-known partisan affiliations for Unicameral legislators.
- The individual level data underlying this release has been extensively cleaned to minimize the random noise inherent in acquiring roll call votes from printed journals.
You can find the data here.
