I disagree George. I think Tsvangirai must withdraw to save as many of the lives of his supporters as he possibly can. He has no chance of winning and being recognised as a winner. Mugabe has already announced that. Zimbabwe will not become a democracy until the post Mugabe era at the earliest. Tsvangirai must also face up to likely imprisonment until the end of Mugabe's reign. For the time being, he must do his best to keep both himself and as many of his supporters as possible alive. There have been quite enough heroic gestures already. Any more would be futile. Those people will be needed in the future.
