Naming a mayoral candidate is a campaign strategy, not an electoral requirement.Yeah, that's not the case, a Mayor is elected in council, so there is no electoral process that requires the naming of mayoral candidates, everyone is a councilllor candidate until they are elected as Mayor, even the Great Zille.
It’s like going into a national election without anyone knowing who your presidential candidate is: technically allowed, but strategically daft.
The ANC never did it because they were assured of victory. The DA forced them to try and name one, a true masterclass of divide and conquer
