Senegal was called to calm today on the eve of a run-off election in which incumbent Abdoulaye Wade, 85, is looking to extend his 12-year rule in a face-off against the full might of the country's opposition. The elections commission urged the candidates not to declare victory prematurely, while observer missions called for a clean vote in the west African country whose reputation for stability is on the line.
