Concept
A lame-duck session of Congress in the United States occurs whenever one Congress meets after its successor is elected, but before the successor's term begins. The expression is now used not only for a special session called after a sine die adjournment, but also for any portion of a regular session that falls after an election. In current practice, any meeting of Congress after election day, but before the next Congress convenes the following January, is a lame-duck session. Prior to 1933, when the 20th Amendment changed the dates of the congressional term, the last regular session of Congress was always a lame-duck session. Congress has held 16 lame-duck sessions since 1940. Recesses preceding lame-duck sessions have usually begun by mid-October, and typically lasted between one and two months. Congress typically reconvened in mid-November and adjourned before Christmas, so that the lame-duck session lasted about a month. Some recesses, however, have begun as early as August 7 or as late as November 3, and ended as early as November 8 or as late as December 31. Lame-duck sessions have ended as early as November 22 and as late as January 3, and have extended over as few as one, and as many as 145, calendar days. Some lame-duck sessions have been held largely for pro forma reasons (e.g., 1948), on a standby basis (e.g., 1940, 1942), or to deal with a single specific matter (e.g., 1954, 1994, 1998). Some sessions, as well, have deferred major matters to the succeeding Congress (e.g., 1944, 1982, 2004), especially when a stronger majority for the same party was in prospect. Most, however, could be regarded as at least moderately productive. When the President has presented an extensive agenda to a lame-duck session controlled by his own party, it has often approved many of his recommendations (e.g., 1950, 2002, 2004), but when he has done so under conditions of divided government, he has had less success, and has often vetoed measures (e.g., 1970, 1974, 1982).
