Long periods of one-party domination, increased average tenure in office for Representatives, and the institutionalization of patterns of succession to the Speakership, have all contributed to a tendency toward leadership stability in the 20th-century House of Representatives. The election of Sam Rayburn (D., Texas) and John McCormack (D., Mass.) to the offices of Speaker and Majority Leader in 1940, of Joseph Martin (R., Mass.) to the office of Minority Leader in 1939, and of Leslie Arends (R., Ill.) to the position of Republican Whip in 1943, mark the beginnings of the longest tenures in these four positions for any incumbents in the history of Congress. When changes in top leadership occur—as with the overthrow of Minority Leader Charles A. Halleck by Republican Representative Gerald R. Ford, Jr., in 1965, or the succession of Majority Leader McCormack to the office of the Speaker in 1962 following the death of Rayburn—the consequences are considerable. In the case of revolt, individual careers are made and broken. The organization and policy orientations of a congressional party may be extensively altered. While orderly succession has less dramatic impact, it too has a significant effect on “who gets what, when and how.” Some members move closer to the seats of power and others fall out of favor. Key committee assignments, and hence the development of entire legislative careers, are likely to ride or fall on the outcomes.
