This is a very clever ploy to greatly increase mad bucket's popularity (and power), whilst at the same time helping Zuma to fade into the background so that he can be replaced.
It is fully orchestrated and funded by the real ANC leadership, and will greatly bolster the popularity of the call to nationalise the country's resources.
Don't for a second think that Zuma and mad bucket are actually fighting, far from it.
If you don't believe me, take a look back at the sudden creation of COPE that was used as a machine to remove the dissidents from the perceived ANC power circle.
Neverunderestimatethesneakiness.
EDIT: Lets not forget that there are now quite a few mines that are owned by cadre's that will have to be bought by the country during the nationalism process.
