The ANC will probably try to shore up the breach by rallying around Zuma until December. They will not heed the by-election warnings of the past week. They believe that if they try to effect an orderly transition, they will be able to save their party and their positions. They will then approach the 2019 election with a new leader and the mantra that all will be well again. They may even succeed, but only if they don't dismantle the networks and lay everything bare to the world. They cannot admit that they allowed this to happen, even if the successor does not emerge from the Zuma camp. Doing that will cripple their movement and guarantee a loss at the polls in 2019.

So, what to do? I think they will do nothing before December. That will embolden the Zuma camp and they will attempt to purge as many opponents as possible and intimidate the rest into silence. I think they will succeed if they are not stopped now.  If they do, they will certainly lose a free and fair election in 2019.
