The Economic Freedom Fighters (EFF) looks set to double the number of votes it achieved in the 2014 general election.
The party has claimed 2 million votes so far in municipal elections.
In 2014, the EFF won just over a million votes.
The party has emerged as kingmakers in several municipalities.
EFF spokesperson Mbuyiseni Ndlozi says, “One of the things that are coming out more crystal is they are rejecting the ruling party, that is why we are not going to work with them. We are carrying a key to the historic classroom where they are going to learn a lesson on humility. We are going to open it and they must walk in, sit down and learn how to be humbler. Never again take people’s votes for granted because we are never indispensable.”
