A "lame-duck" mid-term (Congressional) election is one that occurs when the incumbent President is constitutionally prohibited from seeking re-election in the next scheduled presidential election.
Arguable exceptions are noted below.

* Harry S. Truman was not prevented from running for a 3rd term in 1952 although he chose not to seek re-election.
† Lyndon B. Johnson was not a lame-duck president in 1966, but in March 1968 he chose not to seek
re-election.
± Although Gerald Ford was not a lame-duck president and did run for re-election in 1976, the 1974 mid-term election took place only three months after the resignation of Richard Nixon and only two months following Ford's pardon of Nixon.
