Party systemA party system is a concept in comparative political science concerning the system of government by political parties in a democratic country. The idea is that political parties have basic similarities: they control the government, have a stable base of mass popular support, and create internal mechanisms for controlling funding, information and nominations. The party system concept was originated by European scholars studying the United States, especially James Bryce, Giovanni Sartori and Moisey Ostrogorsky, and has been expanded to cover other democracies.
Opposition (politics)In politics, the opposition comprises one or more political parties or other organized groups that are opposed, primarily ideologically, to the government (or, in American English, the administration), party or group in political control of a city, region, state, country or other political body. The degree of opposition varies according to political conditions. For example, in authoritarian and democratic systems, opposition may be respectively repressed or desired. Members of an opposition generally serve as antagonists to the other parties.
