While Jacob Zuma is sure of a resounding victory, the person who would be his nemesis has urged voters to do the maths to stop the ANC's two-thirds majority.
DA leader Helen Zille on Friday got mired in another war of words with the ANC Youth League's enfant terrible, Julius Malema, calling him "an imbecile", while he retorted that she was "a fake".
Writing in her online newsletter, Zille said Malema was "merely parroting ANC secretary-general Gwede Mantashe when he said the ANC would get "a three-thirds majority".
"Malema believes Zuma is 'unstoppable'. He referred to him as a 'biological tsunami'. That is untrue. If every DA supporter goes to the polls on April 22, we can prevent the 'biological tsunami' from wreaking devastation on South Africa," said Zille.
But speaking in Dutywa, Eastern Cape, on Friday, Malema repeated his invective against Zille, urging the community not to vote for "the racist".
"Zille has no ambition of the people of the Eastern Cape. Her interest is to be premier of the Western Cape. She is not fighting to be president, she is fighting to be Western Cape premier.
"She is fake even she had to go and do plastic surgery, she is not original. If you can fake your own face, what about the policies?
"It means you are a fake. If you look at the original picture, Helen Zille is very ugly. She really looks like a real apartheid agent," he said.
Zille said her supporters' turnout could weaken the ANC's grip on power in provinces such as Gauteng and the Northern Cape.
"If every DA voter turns out, we could win enough votes to be able to form coalition governments. In the Western Cape we could win the province outright," she wrote.
She warned her supporters against a Zuma presidency.
"Make no mistake: if the ANC gets a two-thirds majority with Zuma as president, the consequences will be serious.
"Mr Zuma has no understanding of constitutionalism, the bedrock of our democracy. He has often said that the ANC is more important than the constitution, that opposition parties have no automatic right to exist, and that the powers of the Constitutional Court should be reviewed because judges are 'not God'."
