In 1933, the Twentieth Amendment to the Constitution was adopted. Otherwise known as the Lame Duck Amendment, it reorganized the congressional terms of office and dates of annual convening, eliminating the short (or “lame-duck”) session that had existed up to that time. The amendment was the brainchild of Sen. George W. Norris (R-NE), who argued that lame-duck sessions posed a grave threat to democratic accountability and responsiveness, as they convened after the elections to the next Congress and thus were populated in part by members who were retiring or had lost their reelection bids. As a result, according to Norris, the potential for an agency problem in representation was great in lame-duck sessions. Using the literature on legislative shirking—especially the subliterature on last-term effects—as our theoretical backdrop, we investigate Norris's arguments in detail, examining whether his concerns regarding lame-duck sessions were justified. Using a variety of data and a number of tests, we find little systematic evidence to suggest that exiting members altered their behavior significantly (i.e., shirked) in their last terms in office. In short, the concerns that Norris expressed, such as excessive presidential influence in the legislative process and increased majority-party manipulation of the legislative agenda, were not in fact major problems in lame-duck sessions.
