There are multiple levels to politics in Senegal, one of the oldest — and until recently, most successful — African democracies. There are the power plays and massive government projects reported on by the international media, but also a parallel system of religious affiliations, cultural networks, and tribal ties, little seen by outsiders. To understand the headlines, you need to delve into the latter. The big news this week is that Abdoulaye Wade, Senegal’s geriatric president, is breathing a sigh of relief. The constitution says he can only run for two consecutive terms, but on Friday the constitutional court of this West African country ruled that this did not apply to him. It also decided that Youssou N’Dour, the global pop superstar and the country’s greatest export, who had thrown his hat into the ring, was not eligible to run. Violent protests have flared, in Dakar and elsewhere, in response to the decision and at least three people have been reported dead. Once regarded as one of the most progressive and democratic of African countries, Senegal’s stability is under threat with opposition leaders calling for “popular resistance.”
