Bush's African Legacy

Coming to a movie theater near you: a two-and-a-half minute trailer, narrated by President Bush, showcasing his anti-AIDS programs in Africa.This week, the President is visiting that continent to help give a positive spin to his legacy. He's touring five countries where his anti-AIDS and malaria programs have taken hold.Even his US critics concede he's made a big difference for millions of people, and he's been warmly received in Benin, Tanzania and Rwanda. What are the trade-offs?Do abstinence-only programs do more harm than good? What about poverty and the shortage of food? Do the countries he's not visiting need more help than the five where he's touching down?
