Executive power is exercised by the government. Legislative power is vested in both the government and the two chambers of the legislature.
Liberia is still in transition from dictatorship and civil war to democracy. Liberia's government is based on the American model of a republic with three equal branches of government, though in reality the President of Liberia has usually been the dominant force in Liberian politics. Following the dissolution of the Republican Party in 1876, the True Whig Party dominated the Liberian government until the 1980 coup, eventually creating what was effectively a one-party state.
Currently, no party has majority control of the legislature. The longest serving president in Liberian history was William Tubman, serving from 1944 until his death in 1971. The shortest term was held by James Skivring Smith, who was interim president for all of two months. However, the political process from Liberia's founding in 1847, despite widespread corruption, was very stable until the end of the First Republic in 1980.
The president is elected by popular vote for a six-year term (renewable). The cabinet is appointed by the president and confirmed by the Senate.
Liberia has a bicameral Legislature that consists of the Senate (30 seats; members elected by popular vote to serve nine-year terms) and the House of Representatives (64 seats; members elected by popular vote to serve six-year terms)
