Classification of 2026 primary candidates by ideology in competitive races
Source: Authors' calculations using data from Ballotpedia, candidate websites, social media, and other publicly available data sources.
Note: House candidates coded are from races rated between D+2 and R+2 by the Cook Political Report. Senate candidates coded are from races that were considered the 10 closest contests by Cook. Because only a small number of Senate races fell between D+2 and R+2, the authors chose to include the 10 closest races.
