Which is exactly what you’d expect Jimmy Carter to say.

JOHANNESBURG (CBSDC/AP) — World leaders and joyous, singing South Africans honored Nelson Mandela on Tuesday at a Soweto soccer stadium that was two-thirds full amid cold, driving rain.

The crowds booed South African President Jacob Zuma, who was to give the keynote address at the service, which started an hour late. Many South Africans are unhappy with Zuma because of state corruption scandals, though his ruling African National Congress, once led by Mandela, remains the front-runner ahead of elections next year.

Crowds converged on FNB Stadium in Soweto, the Johannesburg township that was a stronghold of support for the anti-apartheid struggle that Mandela embodied as a prisoner of white rule for 27 years and then during a peril-fraught transition to the all-race elections that made him president.
