Party Realignment in the United States and Britain

Realignment theory is a recent but flourishing sub-branch of the study of American political parties. Over the last thirty years, the original suggestions of its inventor, V. O. Key, have been elaborated and refined in several directions and through several phases, gradually being modified to take variations in historical circumstances more carefully into account. Problems of the same kind often occur, and are likely to prove even less manageable, when efforts are made to apply the theory to another political system and culture as authors from both countries (and from neither) have in recent years tried, more or less explicitly, to use it to explain developments in the British party system. Some techniques travel quite well, and some useful insights can be obtained by looking afresh at familiar patterns in the light of similar experiences elsewhere. But the differences between the two nations and states preclude any rigorous attempt to apply a theory derived from the history of one country with a view to explaining the experiences of the other.
