There's also Derek Hanekom.
I'd say ANC does not enjoy much white support at all. A few percent at most, and the support they do get is probably from the english whites.
As earlier mentioned, the Democratic Alliance totally dominates the white voter base, and has done so at least since the 2004 election. The right wing VF+ is in a distant second place (among Afrikaners only). Probably the religious ACDP following after that.
The only places that differ are a few small towns in the Free State and Limpopo where VF+ enjoys fairly substantial support. They are even bigger than the DA in the town of Wesselbron. But this is to be considered a rare exception.
So VF+ is only backed by the Afrikaners? There is much English descendant support for it?
Slightly off topic, but do English descendants and Afrikaners live in the same general area usually? Are they included in whatever sort of "White state" that VF+ proposes?
VF+ is an Afrikaner party. Anglos usually have little to do with it, to the best of my knowledge.
