It was disillusioning enough that Bush could steal an election last time. But if he actually wins this one squarely, what on earth is the point of democracy? The justification of democracy has always been that it is a mechanism of error-correction. Rather than a way to pick the right leaders, it is a way to ensure that the wrong ones can be held to account; and a leader more wrong than George W Bush is an almost logical impossibility.
Re-electing Bush would be like re-electing Anthony Eden — which leads to a thought experiment: what would have happened had we won at Suez? Would the world have been better or worse?
