Actually it is not so.
The opposition to Mugabe's rule comes from the urban working class in Zimbabwe, and it is they who have borne the brunt of his oppression. As I noted in an earlier post, the open tension between ZANU-PF and the MDC in Zimbabwe is mirrored in the tensions within the tripartite alliance in South Africa.
And now Blade Nzimande has said something on the subject:
'ANC following in Zanu-PF's footsteps'

Blade Nzimande, the SA Communist Party leader, has warned that the ANC government may be falling into the same trap as its Zimbabwean counterparts.
Nzimande on Saturday said the SACP should carefully scrutinise its own alliance partner for signs of similarity between the ANC and the Zimbabwean ruling party, Zanu-PF, which has come under renewed international condemnation for its recent repression of opposition and civil society.
Nzimande coined the phrase "govermentalisation of the national liberation struggle" to warn against the dangers of Zanu-PF's and President Robert Mugabe's hold on power.
