Well it looks like Cape Town is DA all the way. All the results that are out already for around here saw the ANC getting trounced.
The DA was doing extraordinarily well in the other big city areas like Joburg and Pretoria but a lot of the larger areas are slow with results coming out so it will probably slide more in the ANC's favour as time goes on. That said I'm sensing a large overall swing away from the ANC in many areas. Is this a precursor for the way the next general election might go?
