The Purpose of Senatorial Grandstanding during Supreme Court Confirmation Hearings

Abstract US Supreme Court confirmation hearings provide senators with an opportunity to engage a potential justice on a nationwide stage. Senators probe for information about future behavior on the bench. Nominees work through the questions, oscillating between forthcoming and vague responses. Such behavior encourages popular narratives that characterize this intricate dance as a “vapid and hollow charade.” We challenge this wisdom and argue that senators use these hearings to provide meaningful representation to their constituents while simultaneously supporting copartisan efforts regarding the nominee. We examine the exchanges in 185 senator-nominee pairings that span nearly 30 years of confirmation hearings. Our results show that senators from both parties increase their question-asking activity during divided government, when confirmation success is more dubious. Senators from the president’s party ask fewer questions when their constituents support the nominee, however, suggesting that popular support can attenuate this general effect for senators expecting a successful confirmation.
