political cleavage

political cleavage

the division within a political system into competing POLITICAL PARTIES where this leads to a two-party political system, or similar division into competing party blocs (especially a broad left-right division in the pattern of political allegiance), where patterns of allegiance are based primarily on class divisions. For a theorist such as LIPSET (1959), the pattern of political cleavage within a political system is the key to understanding and explaining different types of political system. Thus, whereas STABLE DEMOCRACIES have tended to be characterized by a clearly defined cleavage between class parties, though tempered by the existence of a fundamental CONSENSUS On ‘the rules of the political game’, other kinds of political system have lacked one or both of these requirements.
