In boxing, when a fighter has taken two heavy body blows, he begins to weaken. Now let's apply that analogy to President Zuma. He is a Zulu, a chief. The first body blow that Zuma took was during Nelson Mandela's funeral. In front of the WORLD'S TV CAMERAS he was booed. Biff! That hurt, trust me. Being openly mocked in the eyes of the world.Now fast forward to his sacking of Finance Minister Nene. We all know the result. Zuma was humiliated by his own people as well as by commerce and forced to rescind his decision very publicly, sacking van Rooyen and appointing Pravin Gordhan. Bang! Despite the feeble attempts by the ANC to portray Zuma as 'a brave leader', the truth was plain to see. Minister Nene was MORE IMPORTANT THAN ZUMA. Ouch! And now he has taken more jabs over Nkandla. Also chickened out of a meeting at Davos, having spent millions of the public's money to get there. And while I don't agree with Zuma's mini-me Malema (whose policies can never work), he has at least brought the fight out into the open in Parliament. So get your popcorn folks, and wait for the State of the Nation speech.The boxer is weakening. How long can it be before he finally collapses to the floor and is counted out? Because the truth is, he now a genuine liability for the ANC.
