On Wednesday, millions of South Africans will take to the polls to vote for members of their national assembly, who will then decide on their next president. For the past 30 years, the results have been predictable. The African National Congress, or ANC, which helped free the country from apartheid, has dominated elections ever since. But this time, polls are predicting that will change, as many South Africans are fed up with unemployment, corruption and a host of other issues.
