ABSTRACT
If you ever attend a political convention in the USA, you will be struck by the raucous tumult. You will gape at the disorderly hustle and bustle. Throngs of important-looking people will be scrambling about, some bedecked with television cameras and microphones, others with yellow pads and briefcases, still others with funny hats and strange outfits. Beyond this boisterous turmoil, you will also be struck by the joy and exuberance of those present. People will be slapping each other on the back, shouting hello across large rooms, laughing uproariously in big groups and small. You will not mistake this event for a gathering of morticians or accountants.
