The DA don't know their black (and some white) support was not FOR the party but AGAINST the Anc (Zuma). They have themselves to blame for this. Just last month:
* DA sms - De Lille is bad, we fire her, don't vote GOOD, vote for us
* DA sms - Don't vote for smaller parties, its a wasted vote - vote for us
* DA Tv ad - anc did this, they do that, they will do this, they're planning to do that - vote for us
Can you spot the pattern, not once did they ever sell themselves.
I guess that demostrates the racism of that core group.
