Yes, you can blame them. That is exactly what you should be doing. Also, if we run out of water, we should turn our backs on the DA, and bring in another party. Even if I don't like the ANC I would vote for them to give them a chance to improve on the mistakes of the DA in Cape Town. 

Capetonians cannot run around telling the rest of the country to vote DA because the ANC has failed them, and then continue to vote for the DA when the DA fails Cape Town.
