One of the final reasons that apartheid fell in South Africa was because their ruling class came to the conclusion that it was no longer tenable or defensible. It was no longer working and was doing nothing but lose them friends and allies worldwide. Sound familiar? Maybe like the US now after eight years of Bush?
So, Obama is their choice for change. No, not revolutionary change. But a serious step back from the precipice and time to get rational adults in the White House again. The neocons have been a disaster for the economy, business, and the influence and power of the US. Thus large parts of the ruling class know change is needed now, and Obama is their choice to do it.
