Two-party system
A two-party system is a party system where two major political parties dominate the government. One of the two parties typically holds a majority in the legislature and is usually referred to as the "majority" or "governing party" while the other is the "minority" or "opposition party". Around the world, the term has different senses. For example, in the United States, Jamaica, and Malta, the sense of "two-party system" describes an arrangement in which all or nearly all elected officials belong to one of the only two major parties, and third parties rarely win any seats in the legislature. In such arrangements, two-party systems are thought to result from various factors like winner-takes-all election rules. In such systems, while chances for third-party candidates winning election to major national office are remote, it is possible for groups within the larger parties, or in opposition to one or both of them, to exert influence on the two major parties. In contrast, in the United Kingdom and Australia and in other parliamentary systems and elsewhere, the term "two-party system" is sometimes used to indicate an arrangement in which two major parties dominate elections but in which there are viable third parties which do win seats in the legislature, and in which the two major parties exert proportionately greater influence than their percentage of votes would suggest.
Socialist Party of America
The party changed its name to Social Democrats, USA (SDUSA) by a vote of 73 to 34. Renaming the party as SDUSA was meant to be "realistic". "The New York Times" observed that the Socialist Party had last sponsored a candidate for President in 1956, who received only 2,121 votes and which were cast in only six states. Because the party no longer sponsored candidates in presidential elections, the name "Party" had been "misleading" as "Party" had hindered the recruiting of activists who participated in the Democratic Party, according to the majority report. The name "Socialist" was replaced by "Social Democrats" because many Americans associated the word "socialism" with Soviet Communism. The party also wished to distinguish itself from two small Marxist parties, the Socialist Workers Party and the Socialist Labor Party.
