We’re now a week away from the first Presidential debate, though even calling it the “first” is something of a presumption. Not only does that assume there will be a second (currently scheduled for ABC on 10 September) but it takes for granted that next Thursday’s event will go ahead. A lot can happen in seven days. If you believe the media, Joe Biden is likely to wander off and get lost in his own walk-in wardrobe or Donald Trump will be attacked by a juiced-up Chinese-powered supershark…

There have been a lot of shark attacks, lately. Have you ever noticed that?

Or perhaps neither, but the circumstances of the debate do take us deep into the politics and psychology of the presidential race as it currently stands.
