I disagree with this. It is the DA's job, as formal opposition to the ruling party, to show up the faults of the ANC. It is their job to be the "Jack Russell" of the political structure. They need to make a noise, and get the public involved whenever and wherever the ANC fail (which is all the time). Without this approach, the country will fall further into abyss. Delivering text books to the children who never received them from DOE, was EXCELLENT - it made the ANC realise where they were failing and to what extent. It was an embarrassment to the ANC, which is a good thing....they will think twice about failing in this area again.
Regarding the picture....the ANC realise it could change the minds of the majority black voters next year - those that are fence sitters, and this is why they are having a wobble. A picture speaks a thousand words, the context of the picture happened, and the ANC need to understand that.
