I could never vote for a person I distrusted.  I do not totally distrust the ANC but their leadership I distrust with few exceptions.
At local government level, where we actually, as individuals, can cast a vote for a person, I could even vote for someone who represents a different Party from who I would vote for nationally. That is democracy.  We see this throughout, for example, the UK where trust for a person outweighs the baggage of his Party.
