Julius Malema - South Africa's president-in-waiting?

What will Mandela's death mean for the democracy he created? Julius Malema was the leader of the ANC's youth wing until last year when he was expelled for "sowing divisions in the party". After that he formed the Economic Freedom Fighters - a radical left-wing political party of which he is the self-styled "commander-in-chief." Could he be South Africa's next leader?
