In reply to Duncan Bourne:
There was a bit about this on R4 from a South African journalist. She seemed to think that the parties advocating land grabs seemed to be gaining support. However, her feeling was that lots of people would say they liked those policies but in reality continue to vote for the ANC, mainly for historical reasons (party of Mandela etc). Her concern was that this might change as the ANC core voters died out and a new generation that didn't remember apartheid reached their majority.
