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.
Green Party of the United States
Peter Camejo was quoted in 2002 as claiming that he was a watermelon—green on the outside, but red on the inside. In January 2004, he initiated the Avocado Declaration, which compares Greens to avocados. "An avocado is Green on the outside and Green on the inside". The Declaration goes on to explain that Greens have a vital role in bringing democracy to the otherwise undemocratic two party system of the United States; that the Greens have a unique and independent identity as a third party, which cannot be subsumed into the Republican or Democratic parties; and that they cannot be dismissed by Republican or Democratic critics by implying that they are merely socialists or communists.
