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.
Midwestern United States
The Midwest has been an important region in national elections, with highly contested elections in closely divided states often deciding the national result. In 1860–1920, both parties often selected either their president or vice president from the region.
One of the two major political parties in the United States, the Republican Party, originated in the Midwest in the 1850s; Ripon, Wisconsin had the first local meeting while Jackson, Michigan had the state county meeting of the new party. Its membership included many Yankees who had settled the upper Midwest. The party opposed the expansion of slavery and stressed the Protestant ideals of thrift, a hard work ethic, self-reliance, democratic decision making, and religious tolerance.
