A partisan is a committed member of a political party or army. In multi-party systems, the term is used for politicians who strongly support their party's policies and are reluctant to compromise with their political opponents. A political partisan is not to be confused with a military partisan.
In the United States, the meaning of the term has changed dramatically over the last 60 years. Before the American National Election Study began in 1952, an individual's partisan tendencies were typically determined from their voting behavior. Since then, "partisan" has come to refer to an individual with a psychological identification with one or the other of the major parties. Candidates, depending on their political beliefs, may choose to join a party. As they build the framework for career advancement, parties are more often than not the preferred choice for candidates. Wherein there are many parties in a system, candidates often join them as opposed to standing as an Independent, if that is provided for. In the U.S., politicians have generally been identified with a party. Many local elections in the U.S. are "nonpartisan." A candidate may have a party affiliation but it is not listed on the ballot. Independents occasionally appear in major contests but rarely win. At the presidential level the best independent vote getters were Ross Perot in 1992 and 1996, and John B. Anderson in 1980. President Dwight D. Eisenhower was nonpartisan until 1952, when he joined the Republican Party and was elected president. According to David A. Crockett, "Much of Eisenhower's nonpartisan image was genuine, for he found Truman's campaigning distasteful and inappropriate, and he disliked the partisan aspects of campaigning." With little interest in routine partisanship, Eisenhower left much of the building and sustaining of the Republican Party to his vice president, Richard Nixon. With Eisenhower uninvolved in party building, Nixon became the de facto national GOP leader." Eisenhower's largely nonpartisan stance allowed him to work smoothly with the Democratic leaders Speaker Sam Rayburn in the House, and Majority Leader Lyndon Johnson in the Senate. Jean Smith says that:
Partiinost' is a transliteration of a Russian term from Marxism-Leninism. In Chinese, it is translated as Dangxing. It can be variously translated as party-mindedness, partisanship, or party spirit. The term can refer to both a philosophical position concerning the sociology of knowledge and an official doctrine of public intellectual life in the Soviet Union. The term was coined by Vladimir Lenin in 1895, responding to Peter Struve, to counter what he considered to be the futility of objectivity in political economic analysis. Class interests and material conditions of existence determine ideology, and thus, in a Marxist-Leninist view, true objectivity is not possible in a society of antagonistic classes. Marxists, in Lenin's view, should openly acknowledge their partisanship on the side of proletarian revolution. Bourgeois emphasis on the normative goal of objectivity is thus considered to be delusional. In this sense, partiinost is a universal and inevitable element of political and ideological life, but its presence is not always acknowledged, or is often flatly denied, by the ruling class. Descriptively, partiinost was not a novel concept, and had been described in different words by Thrasymachus, Xenophanes, and Karl Marx. However, Lenin's term has a normative element that was not present in prior descriptions of the phenomenon. In other words, Lenin insisted that partiinost' should be publicly expressed whenever possible. A clear expression of partiinost can be found in its entry in the Great Soviet Encyclopedia:
partiinost. Defending and substantiating the goals and tasks of the working class and the policies of the Communist Party, Marxist-Leninist theory mercilessly criticizes the exploiters' system, its politics, and its ideology. ... By contrast, the bourgeoisie, whose interests conflict with those of the majority, is forced to hide its self-seeking aspirations, to pretend that its economic and political aims are those of society as a whole, and to wrap itself in the toga of non-partisanship Partiinost' is also used by Lenin in Materialism and Empirio-criticism to refer to the concept of philosophical factionalism, which he defined broadly as the struggle between idealists and materialists. The term is also commonly used in modern Russian to describe political affiliations.
