The victory of the African National Congress (ANC) party in Kwa-Zulu Natal in the April elections of this year may have signaled a sea-change in local politics there, but the individual popularity of Jacob Zuma (who is tribal Zulu) as ANC leader may instead be the explanation. The latter is what the Inkatha Freedom Party (IFP) leadership is betting on as they have rejected an offer to unite with the ANC.
The IFP is a swing party these days, friendly with but independent of the "elephant" that is the ANC, and is at the same time willing to side with the Democratic Alliance to keep some limits on what could devolve into a one-party state if unchecked.
It is better by far to be the loyal opposition than to be an insignificant part of the elephant, and it is good that IFP leadership recognizes that. Bravo.
