What do you suppose they're all saying to each other as they laugh and smile and shake hands after the debates?

The candidates, their wives, their kids and aunts and uncles and cousins and all the other members of their supporting entourages: what sort of remarks are they making to the opposing camp as they greet one another on camera immediately after their debates? They can’t be thinking anything terribly friendly about the opposition, and yet for the benefit of the audience they all appear to be concentrating on looking delighted with present company.

Are they swapping jokes, commenting on the weather, complimenting one another’s attire and hairstyles, muttering empty inanities? Are they saying the same sorts of things you’d hear if you were close enough to the chorus in a village crowd scene at the opera?

Are their lines rehearsed?
