Here is a link to a PDF I received. Link I feel this sets out the worst case.

A selected quote "By 2010 the key functions of Government are all under severe pressure.
Then the electricity crisis of 2008 triggered a reaction. Every household was affected and the mismanagement and
cover up of dwindling coal stock piles became common knowledge. This was followed by a flood of information about
the status of dams and rivers that impacted on the supply of fresh water. Next to this, the sewage problem that had
been building up for years suddenly showed its ugly head.
What paralysed the government of President Jacob Zuma was that it all happened at the same time."

How can we make a difference if we can't change the ruling party of SA
