He is dreaming big time..
Half as many votes as the ANC?.... so he wants to get 30% of the national vote, he is basically saying he wants to annihilate all other opposition parties pretty much, when there is less than 12months to the election, AND the majority of the electorate know he is a corrupt lying fscktard.
If he manages to get a party together (and thats a big IF in my mind), and he manages to contest the elections at all, I would be surprised if he manages to get more than 5% of the vote, and that 5% will come directly from the ANC... so IF miracles happen, it will ultimately be a good thing for this country as it will weaken the hold the ANC has already. I very much doubt it will make a significant difference to the DA's percentages.
