“…Perhaps unsurprisingly, when examining Senate behavior during confirmations research finds that ideological distance between a senator and the nominee largely explains votes on confirmation (Cameron, Cover, and Segal 1990;Epstein et al 2006;Moraski and Shipan 1999;Segal, Cameron, and Cover 1992;Songer 1979).While ideological distance remains a prominent factor in Senate votes, however, research increasingly considers external factors altering the judicial selection environment. Procedural changes in the Senate and heightened interest group influence contribute to a "hyperfixation" on judges' ideology, overshadowing other considerations (Cameron, Kastellec, and Park 2013;Farganis and Wedeking 2014;Steigerwalt 2010; see also Bird and McGee 2022;Hollis-Brusky 2015;Scherer and Miller 2009). Interest group mobilization and lobbying, as shown by Caldeira and Wright (1998) and Segal, Cameron, and Cover (1992), impact senators' decisions.…”
