Bill Clinton and George Bush reveal their friendship when they appear together on TV. So it seems, at least. Perhaps they will cause world peace together but something is odd about this caucus of ex presidents. It is as though Clinton has embraced the devil vs the rehabilitation of Bush. The presidential campaign costs 3 billion dollars and yet this could swing voters, but which way is anyone’s guess. It is democracy in a bottle, diplomatic sages warning the next generation of bucks about to debate with each other.
