Government of Senegal
Senegal is a secular republic with a strong presidency, weak legislature, reasonably independent judiciary, and multiple political parties. Senegal is one of the few African states that has never experienced a coup d’etat. As noted above, power was transferred peacefully, if not altogether democratically, from Senghor to Diouf in 1981, and once again, this time in fully democratic elections, from Diouf to Wade in March 2000.

The President is elected by universal adult suffrage to a 5-year term. The unicameral National Assembly has 120 members, who are elected separately from the President. The Socialist Party dominated the National Assembly until April 2001, when in free and fair legislative elections, President Wade’s coalition won a majority (89 of 120 seats). The Cour de Cassation (Highest Appeals Court, equivalent to the U.S. Supreme Court) and the Constitutional Council, the justices of which are named by the President, are the nation's highest tribunals. Senegal is divided into 10 administrative regions, each headed by a governor appointed by and responsible to the President. The law on decentralization, which came into effect in January 1997, distributed significant central government authority to regional assemblies.

Senegal’s principal political party was for 40 years the Socialist Party (PS). Its domination of political life came to an end in March 2000, when Abdoulaye Wade, the leader of the Senegalese Democractic Party (PDS) and leader of the opposition for more than 25 years, won the presidency. Under the terms of the 2001 constitution, future presidents will serve for 5 years and be limited to two terms. Wade was the last President to be elected to a 7-year term.

President Wade has advanced a liberal agenda for Senegal, including privatizations and other market-opening measures. He has a strong interest in raising Senegal’s regional and international profile. The country, nevertheless, has limited means with which to implement ambitious ideas. The liberalization of the economy is proceeding, but at a slow pace. Senegal continues to play a significant role in regional and international organizations. President Wade has made excellent relations with the United States a high priority.

There are presently some 65 political parties, most of which are marginal and little more than platforms for their leaders. The principal political parties, however, constitute a true multiparty, democratic political culture, and they have contributed to one of the most successful democratic transitions in Africa, even among all developing countries. A flourishing independent media, largely free from official or informal control, also contributes to the democratic politics of Senegal. The country’s generally tolerant culture, largely free from ethnic or religious tensions, has provided a resilient base for democratic politics.
