South Africans go to the polls for the fifth time in the post-apartheid era today in a race that the ruling African National Congress (ANC), the liberation movement that forced the end of minority white rule in 1994, is nearly guaranteed to win.

South Africans will elect all 400 members of the National Assembly, by proportional representation on a closed-list basis (which may explain, in part, the hierarchical party strength of ANC governance). They will also elect governments in South Africa’s nine provinces.

Here’s the current breakdown:

Notably, it’s the first election that will feature the ‘born-frees,’ the generation of South Africans who were born after the end of apartheid rule. Though they’re only 2.5% of the electorate today, they’ll become an increasingly vital demographic, and they might well change the face of South African politics over the next decade.

Jacob Zuma, the president since 2009, is leading the ANC campaign, despite his relative unpopularity as South Africans face dwindling economic growth, rising unemployment and the sense that the ANC is more interested in maintaining — and abusing — power than attending to the pressing policy concerns of most South Africans. Zuma’s spending on ‘security improvements’ to his home at Nkandla has captured the widespread disgust of much of the electorate. His government’s handling of a mining strike at Marikana two years ago ended with a clash with police that killed 44 people in the worst state-sponsored violence since the apartheid era. The fallout has severely strained the so-called tripartite alliance among the ANC, the Communist Party of South Africa and the Congress of South African Trade Union (COSATU).

Notwithstanding those concerns, the ANC is almost assured of victory, thanks to its role as the liberation movement that ended apartheid under the mythic leadership of former president Nelson Mandela, who died late last December. The biggest question is whether the ANC will achieve the support of at least two-thirds of the electorate — it could win just 60% (or even less) of the vote.

The chief opposition party, the Democratic Alliance (DA), seems set to increase its support to a historically high level, possibly more than 20% or even 25%. Continue reading South Africa votes in 5th post-apartheid election: what you need to know →
