Things are changing albeit at a snail's pace and the ANC will get its own. In fact, all the other parties will get their rewards depending on how they treat their voters/ population. Politics are a dirty game and no party is squeaky clean, they are all the same but others do a better job of soothing its members and the country at large.
Anyway, I personally think this e-toll saga is good for the country's image cause it shows that we as the population will not take things lying down. Isn't this part of a democracy? Everywhere in the world there are protest and challenges to different governments and we are no different.
