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.
Non-partisan democracy
The Confederate States of America had no political parties during its entire existence from 1861 to 1865. Despite political differences within the Confederacy, no national political parties were formed because they were seen as illegitimate. "Anti-partyism became an article of political faith." Without a two party system building alternative sets of national leaders, electoral protests tended to be narrowly state-based, "negative, carping and petty". The 1863 mid-term elections became mere expressions of futile and frustrated dissatisfaction. According to historian David M. Potter, this lack of a functioning two-party system caused "real and direct damage" to the Confederate war effort since it prevented the formulation of any effective alternatives to the conduct of the war by the Davis administration.
