Minority Status,Ideology, or Opportunity: Explaining the Greater Retirement of House Republicans

Republicans in the U.S. House of Representatives tend to retire at a higher rate than Democrats—a fact with potentially important electoral and policy ramifications—but research on the possible explanations for this partisan disparity has been scarce. I test various explanatory hypotheses using multilevel statistical analyses and find that Republicans are more likely to retire—not because they have been the predominant minority party, had more political opportunities, or had different private‐sector experiences, but because they harbor more conservative ideologies than their Democratic colleagues.
