This is the information that I have found searching the web:
-The Republican Party traces its roots to the 1850s, when antislavery leaders (including former members of the Democratic, Whig, and Free-Soil parties) joined forces to oppose the extension of slavery into the Kansas and Nebraska territories by the proposed Kansas-Nebraska Act. At meetings in Ripon, Wisconsin (May 1854), and Jackson, Michigan (July 1854), they recommended forming a new party, which was duly established at the political convention in Jackson.
-Of the three important American parties which have called themselves Republican,' this article deals only with that one which was organized during the years 1854 to 1856 and has been in control of the government of the United States during the larger portion of the half century since the presidential election of 1860 Origin and Character. - Sectionalism, the movement which tended to break the Union into two separate republics, one based on free labour, the other on that of slaves, had gained before the middle of the 19th century such headway as to compel a reconstruction of the party system. The beginning of this reconstruction was heralded by the rise of the Liberty party, in 1840, its completion by the disruption in 1860 of the Democratic party along sectional lines, and the election of Abraham Lincoln by a sectional vote.

Ghana
Ghana maintains close and friendly relations with its West African neighbours, largely through the regional organisation Economic Community of West African States (ECOWAS), in which it is a key player. President Kufuor was the Chair of ECOWAS in 2003/4 and during that time he played an active role in attempting to resolve the crises in Liberia and Côte d’Ivoire.
On the wider African stage, Ghana plays a leading role in the African Union (AU) and has been a major supporter of NEPAD, the AU’s flagship development plan. Ghana was one of the first 4 countries to be subject to NEPAD’s African Peer Review Mechanism. The review mechanism report was released in June 2005 and is available on the NePAD website (www.nepad.org). In January 2007 Ghana became the Chair of the African Union, a nomination seen as fitting in the year that Ghana celebrated its 50th anniversary.

Ghana's political system compares the United states political system because in Africa the rules (laws) differ. In the United States the laws of the politicians basically state that the two parties (democratic and republic) are separated by statuses such as money and economy. In Ghana everyone is willing to work together as one which is why they are so successful. The leaders of Africa are chosen by consensus vote. The president of Ghana has been elected to the presidency of the African Union,” Alpha Oumar Konare, the AU's chief executive, told reporters in the Ethiopian capital, Addis Ababa. Just the same as we do over here. Ghana's construction is similar to the united states because of the closeness of laws and way of election.
